You don t import scripts in Python you import modules  Some python modules are also scripts that you can run directly  they do some useful work at a module-level    In general it is preferable to use absolute imports rather than relative imports   toplevel package   --   init   py  -- moduleA py  -- subpackage      --   init   py      -- moduleB py   In moduleB   from toplevel package import moduleA   If you d like to run moduleB py as a script then make sure that parent directory for toplevel package is in your sys path

From the docs   from    import scriptA   You can do this in packages  but not in scripts you run directly  From the link above      Note that both explicit and implicit relative imports are based on the   name of the current module  Since the name of the main module is   always    main     modules intended for use as the main module of a   Python application should always use absolute imports    If you create a script that imports A B B  you won t receive the ValueError

If you want to run the script directly  you can    Add the FolderA s path to the environment variable  PYTHONPATH   Add the path to sys path in the your script    Then   import module you wanted
