Obtaining sports data from an API using Python requests
As a data scientist, the ability to obtain data through an API is a critical skill. In this post, I provide a brief tutorial on obtaining soccer data from API-FOOTBALL, a RESTful API hosted by the RapidAPI marketplace. This tutorial follows the general method used in my fourth project completed during the Flatiron School Data Science Bootcamp, in which I explored several ML algorithms for determining the outcome of English Premier league matches using in-game statistics. I won’t discuss the project findings in this post, but feel free to check out the repository here.
Step 1: Create a RapidAPI account and subscribe to API-FOOTBALL
Once you’ve created an account and subscribed, you will be able to access your API key, which you’ll need for making calls to the API.
Step 2: Import necessary packages for working in Python
For this tutorial, we’ll need to import the requests, json, and **pandas **libraries.
Requests is a library that facilitates making http requests with Python. Json is a module that facilitates working with JSON data (the data returned from our API calls will be in JSON). And of course, pandas will help us display and manipulate the data.
Step 3: Store your API key in a private folder
Remember, you never want to hard-code your API keys/tokens, since anyone will be able to see and use them if you make your project public on GitHub or elsewhere.
This is my preferred method for storing/using API keys & tokens: I opt to store my personal API key in a folder named ‘.secret’ in my personal user folder on my C: drive. If you go this route, your file path to this folder will look something like this:
“/Users/{your_username}/.secret/”
Using your favorite text editor, you can then create a .json file (I named mine “api_football.json”) that contains a dictionary with a single key-value pair representing your API key:
There! Now, your API key will be located at the following file path:
“/Users/{your_username}/.secret/api_football.json”
And your actual API key won’t need to appear anywhere in your project code! If the specific API you’re accessing requires more keys/tokens, you can simply add more key-value pairs to the dictionary in your JSON file!

Pdf2gerb: Perl Script Converts PDF Files to Gerber format
pdf2gerb
Perl script converts PDF files to Gerber format
Pdf2Gerb generates Gerber 274X photoplotting and Excellon drill files from PDFs of a PCB. Up to three PDFs are used: the top copper layer, the bottom copper layer (for 2-sided PCBs), and an optional silk screen layer. The PDFs can be created directly from any PDF drawing software, or a PDF print driver can be used to capture the Print output if the drawing software does not directly support output to PDF.
The general workflow is as follows:
- Design the PCB using your favorite CAD or drawing software.
- Print the top and bottom copper and top silk screen layers to a PDF file.
- Run Pdf2Gerb on the PDFs to create Gerber and Excellon files.
- Use a Gerber viewer to double-check the output against the original PCB design.
- Make adjustments as needed.
- Submit the files to a PCB manufacturer.
Please note that Pdf2Gerb does NOT perform DRC (Design Rule Checks), as these will vary according to individual PCB manufacturer conventions and capabilities. Also note that Pdf2Gerb is not perfect, so the output files must always be checked before submitting them. As of version 1.6, Pdf2Gerb supports most PCB elements, such as round and square pads, round holes, traces, SMD pads, ground planes, no-fill areas, and panelization. However, because it interprets the graphical output of a Print function, there are limitations in what it can recognize (or there may be bugs).
See docs/Pdf2Gerb.pdf for install/setup, config, usage, and other info.

Create Pagination Using jQuery
In this article, we will see how to create pagination using jquery. We will create jquery pagination using multiple ways. You can create pagination using different ways like creating pagination using simple HTML, you can create pagination in laravel using paginate() method. Also, create pagination laravel livewire, pagination using bootstrap.
We will create simple jquery pagination. Also, create pagination using jquery without a plugin and create jquery pagination with next and previous buttons
So, let's see dynamic pagination in jquery and bootstrap pagination in jquery
Example:
In this example, we will create pagination using jquery without using a plugin. Also, you can customize the pagination.

Basic Data Types in Python | Python Web Development For Beginners
At the end of 2019, Python is one of the fastest-growing programming languages. More than 10% of developers have opted for Python development.
In the programming world, Data types play an important role. Each Variable is stored in different data types and responsible for various functions. Python had two different objects, and They are mutable and immutable objects.

III Built-in data types in Python
Mutable objects
The Size and declared value and its sequence of the object can able to be modified called mutable objects.
Mutable Data Types are list, dict, set, byte array
Immutable objects
The Size and declared value and its sequence of the object can able to be modified.
Immutable data types are int, float, complex, String, tuples, bytes, and frozen sets.
id() and type() is used to know the Identity and data type of the object
a**=25+**85j
type**(a)**
output**:<class’complex’>**
b**={1:10,2:“Pinky”****}**
id**(b)**
output**:**238989244168
Built-in data types in Python
a**=str(“Hello python world”)****#str**
b**=int(18)****#int**
c**=float(20482.5)****#float**
d**=complex(5+85j)****#complex**
e**=list((“python”,“fast”,“growing”,“in”,2018))****#list**
f**=tuple((“python”,“easy”,“learning”))****#tuple**
g**=range(10)****#range**
h**=dict(name=“Vidu”,age=36)****#dict**
i**=set((“python”,“fast”,“growing”,“in”,2018))****#set**
j**=frozenset((“python”,“fast”,“growing”,“in”,2018))****#frozenset**
k**=bool(18)****#bool**
l**=bytes(8)****#bytes**
m**=bytearray(8)****#bytearray**
n**=memoryview(bytes(18))****#memoryview**
Numbers (int,Float,Complex)
Numbers are stored in numeric Types. when a number is assigned to a variable, Python creates Number objects.
#signed interger
age**=**18
print**(age)**
Output**:**18
Python supports 3 types of numeric data.
int (signed integers like 20, 2, 225, etc.)
float (float is used to store floating-point numbers like 9.8, 3.1444, 89.52, etc.)
complex (complex numbers like 8.94j, 4.0 + 7.3j, etc.)
A complex number contains an ordered pair, i.e., a + ib where a and b denote the real and imaginary parts respectively).
String
The string can be represented as the sequence of characters in the quotation marks. In python, to define strings we can use single, double, or triple quotes.
# String Handling
‘Hello Python’
#single (') Quoted String
“Hello Python”
# Double (") Quoted String
“”“Hello Python”“”
‘’‘Hello Python’‘’
# triple (‘’') (“”") Quoted String
In python, string handling is a straightforward task, and python provides various built-in functions and operators for representing strings.
The operator “+” is used to concatenate strings and “*” is used to repeat the string.
“Hello”+“python”
output**:****‘Hello python’**
"python "*****2
'Output : Python python ’
