=Python= It is an easy to learn, powerful programming language. It has efficient high-level data structures and a simple but effective approach to object-oriented programming.

The Python interpreter and the extensive standard library are freely available in source or binary form for all major platforms from the Python Web site, http://www.python.org/psf./

Scientific Python
Python allows you to split your program in modules that can be reused in other Python programs. It comes with a large collection of standard modules that you can use as the basis of your programs .Python is an interpreted language, which can save you considerable time during program development because no compilation and linking is necessary. It is also a handy desk calculator.

Python enables programs to written compactly and readably. Programs written in Python are typically much shorter than equivalent C or C++ programs.

In Python data types are inbuilt. Declaration of variables is not required and memory management is automatic. Whatever value we assign to the variable i.e. integer, floating number or complex number ,the data type of variable will be the same.

Variable
A variable is a named unit of storage or it is a storage location that contains a data value. This value may change during the execution of the program. The value of a variable may be String   ‘hello’ Integers   45 Floating point number  56.7]]
