traceback.print_exc() python question
I am using the following line of code in IDLE to print out my traceback in an eception:
traceback.print_exc()
For some reason I get the red text error message, but then it is followed by a blue text of "None".
Not sure what that None is about, any ideas?

print_exc() prints formatted exception to stderr. If you need string value, call format_exc()

print_exc() doesn't return anything, which in Python is actually returning None. Looks like IDLE is showing you the None it returned.
