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\Functions\,
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.
