What Is Python?

 Python is a popular programming language. It was created by Guido van Rossum, and released in 1991.

It is used for:

  • web development (server-side),
  • software development,
  • mathematics,
  • system scripting.

What can Python do?

  • Python can be used on a server to create web applications.
  • Python can be used alongside software to create workflows.
  • Python can connect to database systems. It can also read and modify files.
  • Python can be used to handle big data and perform complex mathematics.
  • Python can be used for rapid prototyping, or for production-ready software development.

Why Python?

  • Python works on different platforms (Windows, Mac, Linux, Raspberry Pi, etc).
  • Python has a simple syntax similar to the English language.
  • Python has syntax that allows developers to write programs with fewer lines than some other programming languages.
  • Python runs on an interpreter system, meaning that code can be executed as soon as it is written. 
  • This means that prototyping can be very quick.
  • Python can be treated in a procedural way, an object-orientated way or a functional way.
Good to know

  • The most recent major version of Python is Python 3, which we shall be using in this tutorial. However, 
  • Python 2, although not being updated with anything other than security updates, is still quite popular.
  • In this tutorial Python will be written in a text editor. It is possible to write Python in an Integrated 
  • Development Environment, such as Thonny, Pycharm, Netbeans or Eclipse which are particularly useful when managing larger collections of Python files.

Python Syntax compared to other programming languages

  • Python was designed for readability, and has some similarities to the English language with influence 
  • from mathematics.
  • Python uses new lines to complete a command, as opposed to other programming languages 
  • which often use semicolons or parentheses.
  • Python relies on indentation, using whitespace, to define scope; such as the scope of loops, functions and 
  • classes. Other programming languages often use curly-brackets for this purpose.

In Python How To Find The Factorial Of A Number.?

  "copy" this given code and "paste" it on the python display to run the programme.   Here, i will show it by TWO methods. ⇒  FIRST METHOD  👇 n = int(input("Enter Number:")) fact = 1 while(n >=2):     fact = fact*n     n-=1 print("Factorial=" ,fact) ⇒ SECOND METHOD  👇 n = int(input("Enter Number:")) fact = 1 for i in range(n,1,-1):     fact = fact*i print("Factorial=" ,fact)
