Python, for easy programming

Python code must be indented
(Monty Python at work )

Python is an interpreted language widely used, one of the easiest to learn and use.
A day is enough to start programming with Python and you can write scripts in a few hours while you need for days with other languages​​. It has powerful features such as lists, tuples, dictionaries that allow you to translate your ideas into lines of code directly.
The lists are integrated and made it a successor to the Awk and any other word processor language.

There is a version for Windows, Linux and other platforms.

The name is a tribute to the comedy group "Monty Python", but the same name snake is still became the symbol of the language.

Features

• Python is an object oriented, interpreted language.
• Variables are dynamic, the type is not declared and may change.
• Indentation is used for block recognition and this is unic to Python.
• Tuples are variables or object packed all together, for functions' return, for example.
• Lists and dictionaries are other built-in composed objects.
• Functions may be embedded inside other functions.
• Can be extended with C modules.

Python 3

Version 3.0 changes the syntax of the language which makes it partially incompatible with the previous ones.

• print x is replaced by print (x).
• Two types of string, data str and not compatible.
• Lists are replaced by views and iterators.

Sample code

Displaying chars of a string.

s = "demo"
for c in s:
print c

Displaying elements of a list.

listdemo = [1,2,3] + [4,5]
subdemo = listdemo[1:3]
for num in subdemo:
    print num
>>> should print: 2 3 4
