This is a good question to ask-- you are discovering an important Python convention!
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.
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
Attributes.py should be
Thieves.py should be
Good luck with your Python journey-- Kenneth is a great teacher and has lots of knowledge about multiple resolution order in objects.
