I have everything stored in one giant file, and it's quite inconvenient. And all because I can't import other files, it just doesn't see them, no way. init.py or without it doesn't give anything. Someone help me deal with this madness. I didn't even think that such a problem could arise, in all other languages ​​the file is connected to the file with just one line.

I have even abandoned subdirectories, everything is in one directory, and still python does not see anything except one executable file.

I just don't understand what could be wrong with this code:

from second_file import MyClass
