How to make an import in Python?

Question

Python

There are three py files: the main.py file, which is in dir_1, the a.py file, and the b.py file, which are in dir_2, which in turn is in dir_1.
The file a.py imports b.py and main.py imports a.py.
And when main.py is activated, the error 'ModuleNotFoundError: No module named “b” ' is thrown. Is there any way to fix this error. Or you need to change the structure of the files.

Answer 1

Add . before b
