I have a new MacBook Air with the M1 chip. I downloaded Python (2.7, 3.8, 3.9) and wrote the simplest Python program possible: print (‘Hello World’). It runs fine under IDLE. But when I double-click on this script, python laucher opens, but it does NOT open a terminal window in which the program should run. I get some microsecond flash on the screen, and then nothing. By the way, Python Launcher shows its preferences, which are the factory settings with Run in Terminal Window checked.
If anyone knows how to fix this, please respond.
