[Python] Running Python Modules (-m) - Relative Path Error - Python 3.12.8

What do I want?


Run my project1 package as follows:

(.venv) C:\Users\trg\Escritorio\project1> python -m src.project1.__main__


also understand once and for all how Python execution paths work.

• 
  Why does it work in PyCharm but fail in CMD?
  
  
• 
  What is the recommended way to organize and import modules so that -m always resolves to identical paths in IDEs and terminals?

I ran this command python -m src.project1.__main__ from different paths (within the project), but always got the same error.

I expected my program's interface to start (just like it does when I run it in PyCharm)
