*PROGRAM TO FIND FACTORIAL OF A NUMBER(I HAVE WRITTEN IT ON GEDIT)*

This program is irrelevant. Your question has nothing to do with factorial of numbers. It is about getting input from the user. As you ask:

HOW TO ASK INPUT FROM USER THEN?

The answer is:

Do not use input, as it is dangerous and should not used. Use raw_input instead.

py> answer = raw_input("what is your name? ")
what is your name? Steven
py> print answer
Steven


This works fine. See if you can work out what is going on here, and understand why I say input is dangerous and should be avoided:

py> answer = input("what is your name? ")
what is your name? Steven
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 1, in <module>
NameError: name 'Steven' is not defined
