Bringing two files together

[tjnichols]

I have 2 files that I'm trying to join. I've tried this with the files below. I've also tried this with the files provided by the instructor - still no dice. I've set this up in a virtual environment so I would have more control in what was installed.

class A:
    def spam(self):
        print('A.spam')

from .a import A

class B(A)
    def bar(self):
        print('B.bar')

from .a import A
from .b import B

This is the error I get:

Error:
C:\Python365\python.exe C:/LearningEnv/LearningEnv/10/splitting_a_module_into_multiple_files/TJN_Splitting_Module/__init__.py
Traceback (most recent call last):
  File "C:/LearningEnv/LearningEnv/10/splitting_a_module_into_multiple_files/TJN_Splitting_Module/__init__.py", line 2, in <module>
    from .a import A
ModuleNotFoundError: No module named '__main__.a'; '__main__' is not a package

Process finished with exit code 1

As always - your help is most appreciated!
