You need to either:

1) Put your modules in some directory that's already on your python path.
To find out what your path is, do:

import sys
print sys.path

It should include a directory which ends in "site-packages". Just drop
your modules into that directory.

2) Add the directory where you modules are to your python path. The
easiest way to do this is to set PYTHONPATH in your environment.

You have two choices:

1. In this way you can import single modules (files) in tour folder

import sys
sys.path.append (r'D:\programs\ Functions\')
import my_module_1
import my_module_2

and then use whatever you have in the modules:

my_module_1.my_ function()
print my_module_1.my_ variable


2.
If you add an empty python module called __init__.py inside the folder
D:\programs\Fun ctions\,
then python will handle the folder as a package (i.e. a group of
modules) and you can import
them in this way:

sys.path.append (r'D:\programs\ ')
import Functions # I'm not sure this is needed ...
from Functions import my_module_1, my_module_2

And then use whatever is in your modules as in case 1.

If you put any code in __init__.py, this code will be executed when
the import Functions
statement is executed. This can be handy in some cases, e.g. if you
have subfolders of
Function folder and want to extend sys.path to include all them.

For more details, read the section 6 of Python tutorial.

Re: about python modules

i always just put most of my python files in the c:\python25 directory.
including ones i want to import as modules, since they import from there.
otherwise you can put the file in c:\python25\lib \site-packages

An unmentioned possibility:
Create a file named "whatever.p th" (where the "whatever" is your
choice). The contents of this file should be a line containing the
path to your directory (in your case a single line containing
"D:\programs\Fu nctions" (w/o the quotes).
Put this file in your site-packages file (for windows in your case,
that is C:\Python25\Lib \site-packages
