Python
was developed by “Guido van Rossum”. Also consider as “Father of
python”. In 1989 at National Research institute (NRI)in Netherland.

system group.
The name python was adopted from the some series “monthly python’s
Flying circus”
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..
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.
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.
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.
