I have a Python class called “ClassA” and another Python class which is supposed to import ClassA which is “ClassB”. The directory structure is as follows:

MainDir
../Dir
..../DirA/ClassA
..../DirB/ClassB

How would I use sys.path so that ClassB can use ClassA?

    You really should be using packages. Then MainDir is placed at a point in the file system on sys.path (e.g. …/site-packages), then you can say in ClassB:

    from MainDir.Dir.DirA import ClassA # which is actually a module
    

    You just have to place files named __init__.py in each directory to make it a package hierarchy.
