[New-bugs-announce] [issue43122] Python Launcher doesn't open a terminal window

[Kevin]

New submission from Kevin <kjw at oberlin.net>:

Machine: new MacBook Air with M1 chip, running Big Sur
Downloaded: Python versions 2.7, 3.8, and 3.9
Situation: Programs run just fine IF I run them out of a terminal window (/usr/local/bin/python name-of-python-program). Also programs that use Tkinter windows and don't require a terminal window for input or output run properly.
Problem: Can't launch programs by double-clicking on them. When I try, Python Launcher starts and displays its preferences and there is a microsecond flash of something on the screen that appears to descend into the program icon that was clicked on. 
Note: Playing with a shebang in the program made no difference. Everything works fine when the programs are opened and run in IDLE.
