Let’s get our James Bond swag on shall we? 🕵️‍♀️

Defense departments worldwide are betting on AI to deliver the next generation advanced military technology, and the US is no different. In the US of A, this strategy is being orchestrated by the Joint Artificial Intelligence Center (JAIC), a department under the umbrella of the Department of Defense (DoD) led by Acting Director Nand Mulchandani. And he recently gave his first press conference. And good news…

NLP will play a bigger role in the future of JAIC strategy 🔥. They are working on their own virtual assistant called Fire Support Cognitive Assistant (think Siri with Patriot missiles), which is a software to sort through incoming communications such as calls for artillery or air support. 🧐

This may come as a surprise to many because when we think of national security and AI, it’s hard not to dream of T-1000 SkyNet robots marauding your local 7–Eleven convenience store, but in reality, at least by what they are telling us, NLP will be an important player in their AI investment!

Chromium-net-errors: Chromium Network Errors for Node.js

Chromium Network Errors

Provides Chromium network errors found in net_error_list.h as custom error classes that can be conveniently used in Node.js, Electron apps and browsers.

The errors correspond to the error codes that are provided in Electron's did-fail-load events of the WebContents class and the webview tag.

Features

No dependencies.
100% test coverage.
ES6 build with import and export, and a CommonJS build. Your bundler can use the ES6 modules if it supports the "module" or "jsnext:main" directives in the package.json.
Daily cron-triggered checks for updates on net_error_list.h on Travis CI to always get the most up-to-date list of errors.

Installation

npm install chromium-net-errors --save

import * as chromiumNetErrors from 'chromium-net-errors';
// or
const chromiumNetErrors = require('chromium-net-errors');

Example Use in Electron

import { app, BrowserWindow } from 'electron';
import * as chromiumNetErrors from 'chromium-net-errors';

app.on('ready', () => {
  const win = new BrowserWindow({
    width: 800,
    height: 600,
  });

  win.webContents.on('did-fail-load', (event) => {
    try {
      const Err = chromiumNetErrors.getErrorByCode(event.errorCode);
      throw new Err();
    } catch (err) {
      if (err instanceof chromiumNetErrors.NameNotResolvedError) {
        console.error(`The name '${event.validatedURL}' could not be resolved:\n  ${err.message}`);
      } else {
        console.error(`Something went wrong while loading ${event.validatedURL}`);
      }
    }
  });

  win.loadURL('http://blablanotexist.com');
});

Usage

import * as chromiumNetErrors from 'chromium-net-errors';

Create New Errors

const err = new chromiumNetErrors.ConnectionTimedOutError();

console.log(err instanceof Error);
// true
console.log(err instanceof chromiumNetErrors.ChromiumNetError);
// true
console.log(err instanceof chromiumNetErrors.ConnectionTimedOutError);
// true

function thrower() {
  throw new chromiumNetErrors.ConnectionTimedOutError();
}

try {
  thrower();
} catch (err) {
  console.log(err instanceof Error);
  // true
  console.log(err instanceof chromiumNetErrors.ChromiumNetError);
  // true
  console.log(err instanceof chromiumNetErrors.ConnectionTimedOutError);
  // true
}

Get Error by errorCode

Get the class of an error by its errorCode.

const Err = chromiumNetErrors.getErrorByCode(-201);
const err = new Err();

console.log(err instanceof chromiumNetErrors.CertDateInvalidError);
// true

console.log(err.isCertificateError());
// true

console.log(err.type); 
// 'certificate'

console.log(err.message);
// The server responded with a certificate that, by our clock, appears to
// either not yet be valid or to have expired. This could mean:
// 
// 1. An attacker is presenting an old certificate for which they have
// managed to obtain the private key.
// 
// 2. The server is misconfigured and is not presenting a valid cert.
// 
// 3. Our clock is wrong.

Get Error by errorDescription

Get the class of an error by its errorDescription.

const Err = chromiumNetErrors.getErrorByDescription('CERT_DATE_INVALID');
const err = new Err();

console.log(err instanceof chromiumNetErrors.CertDateInvalidError);
// true

console.log(err.isCertificateError());
// true

console.log(err.type); 
// 'certificate'

console.log(err.message);
// The server responded with a certificate that, by our clock, appears to
// either not yet be valid or to have expired. This could mean:
// 
// 1. An attacker is presenting an old certificate for which they have
// managed to obtain the private key.
// 
// 2. The server is misconfigured and is not presenting a valid cert.
// 
// 3. Our clock is wrong.

Get All Errors

Get an array of all possible errors.

console.log(chromiumNetErrors.getErrors());

CertCommonNameInvalidError

The server responded with a certificate whose common name did not match the host name. This could mean:
An attacker has redirected our traffic to their server and is presenting a certificate for which they know the private key.
The server is misconfigured and responding with the wrong cert.
The user is on a wireless network and is being redirected to the network's login page.
The OS has used a DNS search suffix and the server doesn't have a certificate for the abbreviated name in the address bar.

const err = new Err();

CertDateInvalidError

The server responded with a certificate that, by our clock, appears to either not yet be valid or to have expired. This could mean:
An attacker is presenting an old certificate for which they have managed to obtain the private key.
The server is misconfigured and is not presenting a valid cert.
Our clock is wrong.

Name: CertDateInvalidError

Let’s get our James Bond swag on shall we? 🕵️‍♀️

Defense departments worldwide are betting on AI to deliver the next generation advanced military technology, and the US is no different. In the US of A, this strategy is being orchestrated by the Joint Artificial Intelligence Center (JAIC), a department under the umbrella of the Department of Defense (DoD) led by Acting Director Nand Mulchandani. And he recently gave his first press conference. And good news…

NLP will play a bigger role in the future of JAIC strategy 🔥. They are working on their own virtual assistant called Fire Support Cognitive Assistant (think Siri with Patriot missiles), which is a software to sort through incoming communications such as calls for artillery or air support. 🧐

This may come as a surprise to many because when we think of national security and AI, it’s hard not to dream of T-1000 SkyNet robots marauding your local 7–Eleven convenience store, but in reality, at least by what they are telling us, NLP will be an important player in their AI investment!

Conclusion

Let's get started!

What are Python Arrays?

Arrays are a fundamental data structure, and an important part of most programming languages. In Python, they are containers which are able to store more than one item at the same time.

Specifically, they are an ordered collection of elements with every value being of the same data type. That is the most important thing to remember about Python arrays - the fact that they can only hold a sequence of multiple items that are of the same type.

What's the Difference between Python Lists and Python Arrays?

Lists are one of the most common data structures in Python, and a core part of the language.

Lists and arrays behave similarly.

Just like arrays, lists are an ordered sequence of elements.

They are also mutable and not fixed in size, which means they can grow and shrink throughout the life of the program. Items can be added and removed, making them very flexible to work with.

However, lists and arrays are not the same thing.

Lists store items that are of various data types. This means that a list can contain integers, floating point numbers, strings, or any other Python data type, at the same time. That is not the case with arrays.

As mentioned in the section above, arrays store only items that are of the same single data type. There are arrays that contain only integers, or only floating point numbers, or only any other Python data type you want to use.

When to Use Python Arrays

Lists are built into the Python programming language, whereas arrays aren't. Arrays are not a built-in data structure, and therefore need to be imported via the array module in order to be used.

Arrays of the array module are a thin wrapper over C arrays, and are useful when you want to work with homogeneous data.

They are also more compact and take up less memory and space which makes them more size efficient compared to lists.

If you want to perform mathematical calculations, then you should use NumPy arrays by importing the NumPy package. Besides that, you should just use Python arrays when you really need to, as lists work in a similar way and are more flexible to work with.

How to Use Arrays in Python

In order to create Python arrays, you'll first have to import the array module which contains all the necassary functions.

There are three ways you can import the array module:

By using import array at the top of the file. This includes the module array. You would then go on to create an array using array.array().

import array

#how you would create an array
array.array()

Instead of having to type array.array() all the time, you could use import array as arr at the top of the file, instead of import array alone. You would then create an array by typing arr.array(). The arr acts as an alias name, with the array constructor then immediately following it.

import array as arr

#how you would create an array
arr.array()

Lastly, you could also use from array import *, with * importing all the functionalities available. You would then create an array by writing the array() constructor alone.

from array import *

#how you would create an array
array()

How to Define Arrays in Python

Once you've imported the array module, you can then go on to define a Python array.

The general syntax for creating an array looks like this:

variable_name = array(typecode,[elements])

Let's break it down:

variable_name would be the name of the array.
The typecode specifies what kind of elements would be stored in the array. Whether it would be an array of integers, an array of floats or an array of any other Python data type. Remember that all elements should be of the same data type.
Inside square brackets you mention the elements that would be stored in the array, with each element being separated by a comma. You can also create an empty array by just writing variable_name = array(typecode) alone, without any elements.

Below is a typecode table, with the different typecodes that can be used with the different data types when defining Python arrays:

TYPECODE	C TYPE	PYTHON TYPE	SIZE
'b'	signed char	int	1
'B'	unsigned char	int	1
'u'	wchar_t	Unicode character	2
'h'	signed short	int	2
'H'	unsigned short	int	2
'i'	signed int	int	2
'I'	unsigned int	int	2
'l'	signed long	int	4
'L'	unsigned long	int	4
'q'	signed long long	int	8
'Q'	unsigned long long	int	8
'f'	float	float	4
'd'	double	float	8

Tying everything together, here is an example of how you would define an array in Python:

import array as arr 

numbers = arr.array('i',[10,20,30])


print(numbers)

#output

#array('i', [10, 20, 30])

Let's break it down:

First we included the array module, in this case with import array as arr .
Then, we created a numbers array.
We used arr.array() because of import array as arr .
Inside the array() constructor, we first included i, for signed integer. Signed integer means that the array can include positive and negative values. Unsigned integer, with H for example, would mean that no negative values are allowed.
Lastly, we included the values to be stored in the array in square brackets.

Keep in mind that if you tried to include values that were not of i typecode, meaning they were not integer values, you would get an error:

import array as arr 

numbers = arr.array('i',[10.0,20,30])


print(numbers)

#output

#Traceback (most recent call last):
# File "/Users/dionysialemonaki/python_articles/demo.py", line 14, in <module>
#   numbers = arr.array('i',[10.0,20,30])
#TypeError: 'float' object cannot be interpreted as an integer

In the example above, I tried to include a floating point number in the array. I got an error because this is meant to be an integer array only.

Another way to create an array is the following:

from array import *

#an array of floating point values
numbers = array('d',[10.0,20.0,30.0])

print(numbers)

#output

#array('d', [10.0, 20.0, 30.0])

The example above imported the array module via from array import * and created an array numbers of float data type. This means that it holds only floating point numbers, which is specified with the 'd' typecode.

How to Find the Length of an Array in Python

To find out the exact number of elements contained in an array, use the built-in len() method.

It will return the integer number that is equal to the total number of elements in the array you specify.

import array as arr 

numbers = arr.array('i',[10,20,30])


print(len(numbers))

#output
# 3

In the example above, the array contained three elements – 10, 20, 30 – so the length of numbers is 3.

Array Indexing and How to Access Individual Items in an Array in Python

Each item in an array has a specific address. Individual items are accessed by referencing their index number.

Indexing in Python, and in all programming languages and computing in general, starts at 0. It is important to remember that counting starts at 0 and not at 1.

To access an element, you first write the name of the array followed by square brackets. Inside the square brackets you include the item's index number.

The general syntax would look something like this:

array_name[index_value_of_item]

Here is how you would access each individual element in an array:

import array as arr 

numbers = arr.array('i',[10,20,30])

print(numbers[0]) # gets the 1st element
print(numbers[1]) # gets the 2nd element
print(numbers[2]) # gets the 3rd element

#output

#10
#20
#30

Remember that the index value of the last element of an array is always one less than the length of the array. Where n is the length of the array, n - 1 will be the index value of the last item.

Note that you can also access each individual element using negative indexing.

With negative indexing, the last element would have an index of -1, the second to last element would have an index of -2, and so on.

Here is how you would get each item in an array using that method:

import array as arr 

numbers = arr.array('i',[10,20,30])

print(numbers[-1]) #gets last item
print(numbers[-2]) #gets second to last item
print(numbers[-3]) #gets first item
 
#output

#30
#20
#10

How to Search Through an Array in Python

You can find out an element's index number by using the index() method.

You pass the value of the element being searched as the argument to the method, and the element's index number is returned.

import array as arr 

numbers = arr.array('i',[10,20,30])

#search for the index of the value 10
print(numbers.index(10))

#output

#0

If there is more than one element with the same value, the index of the first instance of the value will be returned:

import array as arr 


numbers = arr.array('i',[10,20,30,10,20,30])

#search for the index of the value 10
#will return the index number of the first instance of the value 10
print(numbers.index(10))

#output

#0

How to Loop through an Array in Python

You've seen how to access each individual element in an array and print it out on its own.

You've also seen how to print the array, using the print() method. That method gives the following result:

import array as arr 

numbers = arr.array('i',[10,20,30])

print(numbers)

#output

#array('i', [10, 20, 30])

What if you want to print each value one by one?

This is where a loop comes in handy. You can loop through the array and print out each value, one-by-one, with each loop iteration.

For this you can use a simple for loop:

import array as arr 

numbers = arr.array('i',[10,20,30])

for number in numbers:
    print(number)
    
#output
#10
#20
#30

You could also use the range() function, and pass the len() method as its parameter. This would give the same result as above:

import array as arr  

values = arr.array('i',[10,20,30])

#prints each individual value in the array
for value in range(len(values)):
    print(values[value])

#output

#10
#20
#30

How to Slice an Array in Python

To access a specific range of values inside the array, use the slicing operator, which is a colon :.

When using the slicing operator and you only include one value, the counting starts from 0 by default. It gets the first item, and goes up to but not including the index number you specify.


import array as arr 

#original array
numbers = arr.array('i',[10,20,30])

#get the values 10 and 20 only
print(numbers[:2])  #first to second position

#output

#array('i', [10, 20])

When you pass two numbers as arguments, you specify a range of numbers. In this case, the counting starts at the position of the first number in the range, and up to but not including the second one:

import array as arr 

#original array
numbers = arr.array('i',[10,20,30])


#get the values 20 and 30 only
print(numbers[1:3]) #second to third position

#output

#rray('i', [20, 30])

Methods For Performing Operations on Arrays in Python

Arrays are mutable, which means they are changeable. You can change the value of the different items, add new ones, or remove any you don't want in your program anymore.

Let's see some of the most commonly used methods which are used for performing operations on arrays.

How to Change the Value of an Item in an Array

You can change the value of a specific element by speficying its position and assigning it a new value:

import array as arr 

#original array
numbers = arr.array('i',[10,20,30])

#change the first element
#change it from having a value of 10 to having a value of 40
numbers[0] = 40

print(numbers)

#output

#array('i', [40, 20, 30])

How to Add a New Value to an Array

To add one single value at the end of an array, use the append() method:

import array as arr 

#original array
numbers = arr.array('i',[10,20,30])

#add the integer 40 to the end of numbers
numbers.append(40)

print(numbers)

#output

#array('i', [10, 20, 30, 40])

Be aware that the new item you add needs to be the same data type as the rest of the items in the array.

Look what happens when I try to add a float to an array of integers:

import array as arr 

#original array
numbers = arr.array('i',[10,20,30])

#add the integer 40 to the end of numbers
numbers.append(40.0)

print(numbers)

#output

#Traceback (most recent call last):
#  File "/Users/dionysialemonaki/python_articles/demo.py", line 19, in <module>
#   numbers.append(40.0)
#TypeError: 'float' object cannot be interpreted as an integer

But what if you want to add more than one value to the end an array?

Use the extend() method, which takes an iterable (such as a list of items) as an argument. Again, make sure that the new items are all the same data type.

import array as arr 

#original array
numbers = arr.array('i',[10,20,30])

#add the integers 40,50,60 to the end of numbers
#The numbers need to be enclosed in square brackets

numbers.extend([40,50,60])

print(numbers)

#output

#array('i', [10, 20, 30, 40, 50, 60])

And what if you don't want to add an item to the end of an array? Use the insert() method, to add an item at a specific position.

The insert() function takes two arguments: the index number of the position the new element will be inserted, and the value of the new element.

import array as arr 

#original array
numbers = arr.array('i',[10,20,30])

#add the integer 40 in the first position
#remember indexing starts at 0

numbers.insert(0,40)

print(numbers)

#output

#array('i', [40, 10, 20, 30])

How to Remove a Value from an Array

To remove an element from an array, use the remove() method and include the value as an argument to the method.

import array as arr 

#original array
numbers = arr.array('i',[10,20,30])

numbers.remove(10)

print(numbers)

#output

#array('i', [20, 30])

With remove(), only the first instance of the value you pass as an argument will be removed.

See what happens when there are more than one identical values:


import array as arr 

#original array
numbers = arr.array('i',[10,20,30,10,20])

numbers.remove(10)

print(numbers)

#output

#array('i', [20, 30, 10, 20])

Only the first occurence of 10 is removed.

You can also use the pop() method, and specify the position of the element to be removed:

import array as arr 

#original array
numbers = arr.array('i',[10,20,30,10,20])

#remove the first instance of 10
numbers.pop(0)

print(numbers)

#output

#array('i', [20, 30, 10, 20])

Conclusion

And there you have it - you now know the basics of how to create arrays in Python using the array module. Hopefully you found this guide helpful.

You'll start from the basics and learn in an interacitve and beginner-friendly way. You'll also build five projects at the end to put into practice and help reinforce what you learned.
