python - Create exception hook in a thread -


the following code works when put in main module, exception hook not called when error occurs in thread, not if put code second time within thread.

any suggestions why?

import sys def myexcepthook(exctype, value, traceback):     if exctype == keyboardinterrupt:         print "handler code goes here"     else:         sys.__excepthook__(exctype, value, traceback)  sys.excepthook = myexcepthook

the thread called follows:

t1 = threadmanager(1, "thread-1", 1) t1.start()   class threadmanager(threading.thread):     def run(self):         print 9_) # should cause error ic caught hook
