Appending to Your Python Path

Question:

How do you append directories to your Python path?

Answer:

Your path (i.e. the list of directories Python goes through to search for modules and files) is stored in the path attribute of the sys module. Since path is a list, you can use the append method to add new directories to the path.

For instance, to add the directory /home/me/mypy to the path, just do:

    import sys
    sys.path.append("/home/me/mypy")
