A. Create a folder which will contain all of your modules. As an example, lets use 'MyModules'

B. Within the folder, save your classes in a py file. You can have more nesting than I'll demonstrate, but for simplicity we will not nest folders in this example.

C. Create another python file in the same directory named __init__.py. Note there are 2 underscores before and after 'init'. Within that file, import the file you need.

The syntax should be 'from FOLDERNAME import FILENAME'

D. Now, from a new python file, you can import your custom classes. Note, if your package isn't recognized, you may need to change the path you're running the file from.
