    If you are a developer and want to grow your programming skills in the modern programming approach, this article is definitely for you. If you have just finished your study and started coding to become a programmer, then this is where you can enhance your skills and add Python to your development career.

    Best Way to Learn Python

    In this article, we will discuss today's programming world’s most popular and rapidly growing programming language, i.e., when we talk about programming in today's time, Python's name definitely comes.

    Developers dominate Python. Python is the leader of the technology world after Java , and this can make you a hero from zero in programming just because of its features. But after these all things, you must be wanted to know what is there in Python which makes it different from all other programming languages and why this is so popular.

    So, we will start with the basics of Python and will cover everything about Python’s unique features and how you can learn Python in the best way.

    What is Python?

    The first question that arises to your mind is obviously what Python is. So, Python is a general-purpose programming language and was first released in 1991. According to Guido van Rossum, the creator of Python, “Python is an interpreted, high-level, object-oriented programming language which has a design philosophy emphasizing code readability, and it often uses English keywords where other programming languages use punctuation.”

    Python supports multiple programming paradigms, including functional, procedural, structured, object-oriented, imperative, and a comprehensive standard library. Python’s core philosophy is summarized in the Zen of Python, which says:

    • Explicit is better than implicit
    • Beautiful is better than ugly
    • Simple is better than complex
    • The complex is better than complicated
    • Readability counts

    Python’s syntax is relatively simple and unique than other languages, which can be learned easily. Python is used for server-side Web development, Software development, Automation, Data Science , Machine Learning, System scripting, etc.

    The queer thing about Python is that it can handle big data and perform complex mathematics. Python uses duck typing and allows programmers to define their own types using classes. Before version 3.0, there were two classes, i.e., old-style and new-style. In Python 3.0, old classes were eliminated.

    Python 3's built-in Types

    Type Mutable Description Syntax example
    Bool immutable Boolean value True False
    byte array mutable Sequence of bytes bytearray(b'Some ASCII') bytearray(b"Some ASCII") bytearray([119, 105, 107, 105])
    bytes immutable Sequence of bytes b'Some ASCII' b"Some ASCII" bytes([119, 105, 107, 105])
    complex immutable A complex number with real and imaginary parts 3+2.7j
    dict mutable An associative array (or dictionary) of key and value pairs; can contain mixed types (keys and values), keys must be a hashable type {'key1': 1.0, 3: False}
    ellipsis An ellipsis placeholder to be used as an index in NumPy arrays ...
    float immutable Floating point number, system-defined precision 3.1415927
    frozenset immutable Unordered set, contains no duplicates; can contain mixed types, if hashable frozenset([4.0, 'string', True])
    int immutable Integer of unlimited magnitude 42
    list mutable A list, can contain mixed types [4.0, 'string', True]
    set mutable Unordered set, contains no duplicates; can contain mixed types, if hashable {4.0, 'string', True}
    str immutable A character string: the sequence of Unicode codepoints 'Wikipedia' "Wikipedia" """Spanning multiple lines"""
    tuple immutable Can contain mixed types (4.0, 'string', True)

    Fundamentals Example of Python Language

    Here is a simple program is written in the Python program to calculate the Average of Numbers in a given list.

    Code:

    n=int(input("Number of elements to be inserted: "))
    a=[]
    for i in range(0,n):
        elem=int(input("Enter element: "))
        a.append(elem)
    avg=sum(a)/n
    print("Average of elements ",round(avg,2))

    Output :

    Number of elements to be inserted: 5
    
    Enter element: 3, 5, 12, 9, 1
    
    Average of elements 15

    Why choose Python over other Languages?

    Python works for different platforms such as Windows, Linux, Mac, Raspberry Pi, etc. Python is very simple that allows developers to write programs in fewer lines. Here we summarize the reasons why you should choose Python over other languages: -

    • Simplicity

    The simplicity, likeness to English, conciseness, readability, and expressiveness make it the perfect choice for rookies.

    • Open-Source and a Large Community

    Python is open-source and has a large community that tries to improve it. A programming community is always beneficial for the availability of many libraries, modules, and packages to help you with your project. Python is ranked by various popular websites, such as the 5th Largest Stack Overflow Community, 4th Most-Used Language at GitHub, and 3rd Largest Meetup Community are some of their examples.

    • Easy to Learn and Code

    Python is straightforward to learn and very popular in programming to have a bright career. With Ruby, Python developers are the second-highest-paid professionals after Swift in the programming world. Python is also used in Cyber Security, which is why to learn.

    • Open-Source Frameworks and Libraries

    Python is great as a scripting language. Some Python frameworks , such as Django, Pylons, Flask , and Web2py , are used in famous online platforms. Django is used on Instagram and Pinterest. So Python is very popular in web development.

    Python frameworks like SciPy and NumPy are used in Artificial Intelligence and Machine Learning. Before Python existed, MATLAB ruled the Artificial Intelligence and Machine Learning world. Still, after Python, it is possible to use a single import statement followed by a function call to perform complex computations.

    • Used with Raspberry Pi

    The other interesting part of Python is Raspberry Pi, a microcomputer similar to the size of a credit card. This is used to make robots, remote-controlled toys, arcade machines, and even cameras. You can explore the world of technical DIYs (Do It Yourself) using Raspberry Pi, and with Sonic Pi, you can even make music.

    Today Python is everywhere, whether it is for startups or corporates. Python is the perfect combination of flexibility and uniqueness, making it a suitable package for any project. Organizations like Disney, Google, and even NASA always focus on talented Python developers .

    These are the several reasons explained. Besides this, the enormous Python community is always available to solve your problem with their strong documentation, tutorials, guides, and examples to help you along the way.

    Benefits of Learning Python

    There are many languages available in the market for web development, but why and how Python differs from them are remarkable factors. The features which make it popular to use are:

    • Python is very easy to code and easier to learn. Its syntax can be learned in just a few hours as the code is quite like English. Python is dynamically typed, which makes it readable.
    • One of the outstanding features of Python is its expressiveness. Any program can be written in Python using local transformations, as Python provides countless constructs that help to focus on the solution rather than the syntax.
    • Python is open-source and freely available. Anyone can download and install it as its community is headed towards one goal, i.e., an ever-bettering Python.
    • Python is the high-level programming language that makes it more developer-friendly.
    • Python is a portable language, so writing different code for different machines is unnecessary.
    • Python is an object-oriented language. Therefore supports all the features of object-oriented and also supports multiple inheritance, unlike Java.
    • Python is an extensible language. You can write in any other language, like C++. Python can be extended to any other language.
    • Python code is embeddable. In simple words, you can put your source code written in Python in any other programming language like C++. This feature allows us to integrate the scripting capabilities of other programming languages into our program.
    • Python is an interpreted language. There is no need for a compilation of programs in Python. An interpreted language executes code line by line, making debugging the code easier.
    • Python supports a large standard library that includes regular expressions, documentation generation, unit testing, web browsers, threading, databases, CGI, email, image manipulation, and a lot of other functionality that can be used to reduce the need to write code for every single thing.
    • Python also supports GUI programming by using Tk to create basic GUIs.
    • Python is a dynamically-typed language, meaning that the value type is decided at runtime, not in advance.

    In summary, Python is:

    • Easy to Use
    • Expressive, High Level, and Interpreted Language
    • Platform Independent
    • Open Source
    • Object-Oriented language
    • Provide huge Standard Library
    • GUI Programming
    • Integrated
