Python Introduction: What is Python?

What is Python?

Python is a famous and widely used programming language. It is high-level programming or scripting language. Python was created by Guido van Rossum in the 1980s at Centrum Wiskunde & Informatica. Python is written in C language and the implantation is known as CPython. Several other implementations are written in PyPy i.e. Python. This famous programming language can run on several operating systems like Windows, Linux, Mac, etc. Python file can be saved with various extensions such as .py, .pyi, .pyc, .pyd, .pyo. Python source code is very much familiar because the script looks like plain English and Mathematical calculation.

Features of Python:

Python is very similar to other programming languages like Perl and PHP. Python acts as an interpreter and it is handled at runtime by that. It has interactivity features so that coders can directly interact with the Python prompt and change their code accordingly. Due to it is an object-oriented programming language, it has the capability of inheritance, encapsulation, etc. Any non-programmer can start Python because it is treated like a beginner’s language as well. Python supports an extensive range of application development, functional, and structured programming approaches. For creating large apps, this interpreted language can be compiled to byte-code. Python is very much flexible with high-level dynamic data types. Python cares about dynamic type checking and spontaneous garbage collection.

Python Applications:

Python is a treading programming language. As per the market trend, it has various applications. Those are given below

  • Web Development
  • Game Development
  • Machine Learning and Artificial Intelligence
  • Data Science and Data Visualization
  • Desktop GUI
  • Web Scrapping Application
  • Business Applications
  • Audio and Video Application
  • CAD Application
  • Embedded Applications

Other Characteristics of Python:

Python is actually designed for software engineers and software programmers. Anyone from a coding language must go for python. Because it is a mandatory skill in all business industries.  All the top 8 companies in the World use Python. Those companies are Google, Facebook, Amazon, Instagram, Spotify, Quora, Netflix, and Dropbox. Python is easy to learn, read, and maintain. Python has few keywords, a simple structure, and well-defined syntax that helps the coders to understand the script easily. Python is very much portable and has an interactive mode that lets the programmers test the code interactively. Python has a feature of shell scripting and provides a better structure, hence it is scalable.

Basic Syntax of Python:

  • Print: print ()
  • Supported Data types: integer, float, string, etc.
  • Comment: # (Single Line), ‘’’ (multiple lines)
  • Arithmetic operators: +, -, *, /, %, **, etc.
  • Comparison operator: ==, <>, >, <, >=, <=, !=, etc.
  • Logical, Membership, and identify operator: and/or/not, in/not in, and is/is not.
  • If statement: if (condition): //print something
  • For loop: for i in range (value):
  • While Loop: while (condition):
  • Functions: def function_name ():

These are some basic syntaxes of Python. It has many more.
