I have updated mac os to Catalina, and now in Finder I can't open my python files with double click.
I usually use IDLE for python 3.7.9. The default application to open .py files is already set to IDLE (3.7.9) but when I double click on my file, nothing is happening.
But it's work if my IDLE isn't opened. I've trying to open with Thonny and it's same: it's doesn't work if Thonny ist opened and it's work if Thonny is not opened.
I can open my files with:
$ idle -e file.py
in Terminal or $ env PATH=/usr/bin:/bin:/usr/sbin:/sbin idle myfile.py
I have only IDLE 3.7.9 and reinstalled (I have deleted other versions)
