sys.exc_info

[Steven D'Aprano]

sys.exc_info() returns three items:

(exception type, exception value, traceback)

https://docs.python.org/2/library/sys.html#sys.exc_info

https://docs.python.org/3/library/sys.html#sys.exc_info



and may be used something like this example:


try:
    something
except:
    exc_type, exc, tb = sys.exc_info()
    print(traceback.extract_tb(tb))
    raise



Why does it return the exception type separately from the exception, when 
the type can be derived by calling `type(exc)`?
