So firstly, I use the first file to import the second using import second_file
then in the second file,
I import the first file with the same way and it works and I also import the third file from the first file BUT when I try to import the first file from the third it doesn't work
So: file1 ----> import second_file
file 2 ----> import first_file
file1 ----> import third_file
file 3 ----> import first_file
THAT IMPORT DOESN'T WORK
