How to ignore one file when having multiple files with same names

Question

My folder tree looks as follows:

• main_folder/
  • .gitignore
  • file1.py
  • secondary_folder/
    • file1.py

I'm trying to ignore only the file1.py that outside the secondary_folder.
Already tried both ./file1.py and main_folder/file1.py and !secondary_folder/file1.py but in all cases it includes both files.

Answer 1

Ignore /file1.py. The leading slash means "the directory where the .gitignore resides".
