Your Data Architecture: Simple Best Practices for Your Data Strategy

If you accumulate data on which you base your decision-making as an organization, you should probably think about your data architecture and possible best practices.

If you accumulate data on which you base your decision-making as an organization, you most probably need to think about your data architecture and consider possible best practices. Gaining a competitive edge, remaining customer-centric to the greatest extent possible, and streamlining processes to get on-the-button outcomes can all be traced back to an organization’s capacity to build a future-ready data architecture.

In what follows, we offer a short overview of the overarching capabilities of data architecture. These include user-centricity, elasticity, robustness, and the capacity to ensure the seamless flow of data at all times. Added to these are automation enablement, plus security and data governance considerations. These points from our checklist for what we perceive to be an anticipatory analytics ecosystem.

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.

Table of Contents  hide

I Mutable objects

II 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 ’

Python+ 101: Most useful data structures and algorithms

Python is undoubtedly one of the most widely used programming languages of this century that has given a whole new perspective to programming in terms of ease of use and intuitiveness. Besides having a rich set of the most common data structures, it provides a number of standard libraries that can greatly reduce the burden of developing codes from scratch for a variety of problems pertaining to different fields. In this tutorial, I will focus on some of the most common problems or should I say, encounters, and their solutions using data structures and algorithms of standard python modules. So let’s dive into the world of “Python+” which is all about adding something more into what we know of Python.

1. N largest or smallest elements in a list, tuple, set or numpy array

In many scenarios, we need to extract the largest or smallest elements in a collection. The nlargest and nsmallest methods of the heapq module of python can be used to obtain N largest and smallest elements in a list. nlargest(n,iterable) and nsmallest(n,iterable) where n is the number of largest or smallest elements that need to be obtained and iterable can be a list, a tuple, a set or a numpy array can be used as follows.

Figure 1. Smallest and largest elements in a list, tuple and array

These methods are faster and more efficient in case more than one largest or smallest elements in a collection is needed. If the single largest or smallest element is needed, the min and max functions in python are more efficient. Note that the _nlargest_ and _nsmallest_ functions always return a list irrespective of the type of the collection.

Data Structures & Algorithm in Python: Everything You Need to Know

Data structures and algorithms in Python are two of the most fundamental concepts in computer science. They are indispensable tools for any programmer. Data structures in Python deal with the organization and storage of data in the memory while a program is processing it. On the other hand, Python algorithms refer to the detailed set of instructions that helps in the processing of data for a specific purpose.

Alternately, it can be said that different data structures are logically utilized by algorithms to work out a particular problem of data analysis. Be it a real-world problem or a typical coding-related question, an understanding of data structures and algorithms in Python is crucial if you want to come up with an accurate solution. In this article, you will find a detailed discussion of different Python algorithms and data structures.

**What are data structures in Python? **

Data structures are a way of organizing and storing data; they explain the relationship between data and various logical operations that can be performed on the data. There are many ways in which data structures can be classified. One way is to categorize them into primitive and non-primitive data types.

While the primitive data types include Integers, Float, Strings and Boolean, the non-primitive data types are Array, List, Tuples, Dictionary, Sets and Files. Some of these non-primitive data types, such as List, Tuples, Dictionaries and Sets, are in-built in Python. There is another category of data structures in Python that is user-defined; that is, users define them. These include Stack, Queue, Linked List, Tree, Graph and HashMap.
