So how can i use it in another module. I tried sys.path.append and give path of my save file but its not working. Can somebody tell me do i have to set Environment variable in windows xp

Answer 1

Use this way:

import sys

then:

sys.path.insert(0,"X")

Where X is the directory you want to import from.

After that you just need to import your custom module:

import X

Thats all.

Answer 2

There is a directory DIR containing our module X: /DIR/X

import sys    
sys.path.insert(0,"DIR")
import X

This imports the module e.g. X =hello.
