An inescapable while loop in Python
fman is programmed in Python. While hunting a bug today, I realised I've been making a mistake for the past 6 years. Consider the following code:
from time import sleep while True: try: sleep(.1) except: pass
What do you think happens when you press
Ctrl+C? I would have
expected to get out of the infinite loop. But it doesn't work! You have
Ctrl+Z to suspend the process.
The reason for this is that the empty
everything, including the
that is raised when you press
Ctrl+C. Instead, what you'll most
likely want is:
try: ... except Exception: ...
This catches the exceptions you're normally interested in but leaves others
except: for me!
