Before we move to Python programming, let's learn what programming is?

What is Programming?

In simple words, It is the process of creating a set of instructions that tells the computer how to perform a task. Programming can be done by using the variety of the computer "languages" such as C, C++, SQL, JAVA, and PYTHON. 

What is mean by programming language?

The computer programming language is any of the various languages (like  C, C++, Java, etc )for expressing a set of detailed instructions for a digital computer. 

What is Python?
Python was created by Guido van Rossum from 1985- 1990. It is the high level, interpreted, general-purpose, and object-oriented programming language. Python is easy to learn, It is a powerful programming language.


Why it is called Python?

When Python founder Guido Van Rossum was beginning implementing the Python, he was also reading the published script from "Monty Python's Flying Circus", a BBC comedy series from the 1970s. Guido Van Rossum thought that he needed a name for a programming language that was unique, very short, and slightly mysterious. so, Guido van Rossum decided to call the language Python. 

Features of Python:-

  • Easy to Learn:-  Python programming has very few keywords, has a simple structure, and a clearly defined syntax. 
  • Easy to read:− Python programming code is more clearly defined and visible to the eyes.
  • Easy to maintain − Python programming source code is fairly easy to maintain.
  • A broad standard library − Python programming language has large quantities of the library that is very portable and cross-platform compatible with UNIX, Windows, and Macintosh.
  • Interactive Mode −Python programming language support for an interactive mode that allows interactive testing and the debugging of snippets of code.
  • Portable − Python programming language can be run on a wide variety of hardware platforms and has the same interface on all the platforms.
  • Extendable − Here is one feature that you can add low-level modules to the Python interpreter. These modules enable the programmers to add or to customize their tools to be more efficient.
  • Databases − Python provides interfaces to all the major commercial databases.
  • GUI(Graphical User Interface) Programming − Python supports GUI(Graphical User Interface) applications that can be created and ported to many system calls, libraries, and windows systems, such as Windows MFC, Macintosh, and the X Window system of Unix.
  • Scalable − Python provides better structure and support for large programs than shell scripting.

2. After downloading, install on the system.

Set Path for Windows:-

1. Copy the python path.

go to the C drive/Users/Lenovo/AppData/Local/Programs/Python/Python37

Note:-

(This is the path of my system and I am Using python 3.7 version<64bit> ).

2.paste that path into the system variable.

Go to the Control Panel/All Control Panel Items/System/Advanced system setting/Environment variable/System variable/click on the path/and paste the link which u have copied/and then click on apply.

How to check if the path is set:-

1.press Windows+R key.

2.Type cmd and search It.

3.Type python and press Enter.
