Why can't I handle a KeyboardInterrupt in python?

Question

I\'m writing python 2.6.6 code on windows that looks like this:

try:
    dostuff()
except KeyboardInterrupt:
    print \"Interrupted!\"
except:
    print \"S         


        

Answer 1

Here's a guess about what's happening:

• pressing Ctrl-C breaks the "print" statement (for whatever reason... bug? Win32 limitation?)
• pressing Ctrl-C also throws the first KeyboardInterrupt, in dostuff()
• The exception handler runs and tries to print "Interrupted", but the "print" statement is broken and throws another KeyboardInterrupt.
• The finally clause runs and tries to print "cleaning up....", but the "print" statement is broken and throws yet another KeyboardInterrupt.
