Python App: When it crashes, is there a way to see any program output?

[komame]

At the moment, very few people use this application, and it's difficult to determine when exactly the crash occurs. Maybe try starting with a simple program that prints something on the screen for a slightly longer period and then waits for user input, for example:

Code:

for i in range(2000):
  print(i)
input()

After running, it should display numbers from 0 to 1999 sequentially, which should take a few seconds. When the display is complete, the program should stop and wait for user input, so it will behave similarly to a freeze.
Check if anything at all appears on the screen.
