python - Ignore passed arguments -

-

is possible ignore passed/overgiven arguments in method?

here example want do:

def event_handler(one, two):    print(one)    print(two)

and @ place:

event_handler(one, two, three)

i mean third argument optional. i've tried in python fiddle, doesn't work without error.

make third default argument

def event_handler(one, two, third = none):

then error handling, default, easy. 

def event_handler(one, two, third = none):    print(one)    print(two)    if (three):         print(three)
