Python expects the "case" of the import
modules to match the case of the source file. PEP-8 (one of our guiding conventions) there is a suggestion that all filenames should be lowercase.
https://www.python.org/dev/peps/pep-0008/#package-and-module-names
quoting this--
Modules should have short, all-lowercase names. Underscores can be used in the module name if it improves readability. Python packages should also have short, all-lowercase names, although the use of underscores is discouraged.
In your example, to make it work, you should do the following renames.
Characters.py
should be characters.py
Attributes.py
should be attributes.py
Thieves.py
should be thieves.py
Good luck with your Python journey-- Kenneth is a great teacher and has lots of knowledge about multiple resolution order in objects.
