WHY PYTHON?? 

Python has some unique features they are:

  • Easy to learn 

  • Clean syntax 

  • Comprehensive standard Library 

  • Excellent documentation 

  • General purpose

 

Features Of Python:

  • Simple and easy to learn:

Python is a simple programming language. When we read Python program,we can feel like reading English statements. The syntax's are very simple and only 30+ keywords are available.When compared with other languages, we can write programs with very less number offline. Hence more readability and simplicity.We can reduce development and cost of the project.

  • Freeware and Open Source:

We can use Python software without any license and it is freeware. Its source code is open,so that we can we can customize based on our requirement.

  • High Level Programming language:

Python is high level programming language and hence it is programmer friendly language. Being a programmer we are not required to concentrate low level activities like memory management and security etc..

  • Platform Independent:

Once we write a Python program,it can run on any platform without rewriting once again. Internally PVM is responsible to convert into machine understandable form.

  • Portability:

Python programs are portable. ie we can migrate from one platform to another platform very easily. Python programs will provide same results on any platform.

  • Dynamically Typed:

In Python we are not required to declare type for variables. Whenever we are assigning the value, based on value, type will be allocated automatically.Hence Python is considered as dynamically typed language.
