Python Introduction

What is Python?

Python is a high-level, interactive, interpreted and object-oriented programming language.
It was created by Guido van Rossum, and released in 1991.

  • Python is High Level - Written in a form that is close to our human language. No particular knowledge of the hardware is needed as high level languages create programs that are portable and not tied to a particular computer or microchip.
  • Python is Interactive – Programmer can interact with the interpreter directly to write your programs using Python prompt.
  • Python is Interpreted − Python is processed at runtime by the interpreter. You do not need to compile your program before executing it.
  • Python is Object-Oriented − Python supports all the Object-Oriented techniques such as Class, Object, Methods, Inheritance ,Encapsulation and Polymorphism

  • What is Scope of Python?

    Python in used to create:

  • Web Applications
  • Chatbots
  • Video Games
  • Automating Application
  • Artificial Intelligence algorithms
  • Desktop Applications..etc..,


  • How easy to learn Python?

  • Python has a simple syntax similar to the English language.
  • No need of programming background.
  • Simplest programming language when compared to all other programming languages.

  • Python Syntax compared to other programming languages

    Example 1: Hello World Program: Java vs Python

    The same program in Python can be coded as below:

      # Sample Code
      print("Hello World")
      
      Output:
      Hello World
    

    Example 2: Swap the 2 numbers : C vs Python


    The same program in Python can be coded as below:

      # Sample Code
      a, b = 6, 13
      a, b = b, a
      print(a, b) 
    
      Output:
      13 6
    

    Example 3: Count total number of times “python” word is displayed: VB Script vs Python

    The same program in Python can be coded as below:

      # Sample Code
      str = "Welcome to Python Tutorials. Python is a general purpose high level
    programming language.We will study about features of Python, use of Python,
    advantages of Python and disadvantages of Python.Thank you" print(str.count("Python") Output: 6
