[Tutor] Regarding python function arguments

[Arijit Ukil]

i am writing following python function:

def my_func (arg1, arg2, arg3):

however, I am not always going to pass all the arguments. sometimes only 
arg1 is passed, sometimes arg1 and arg2 are passed; sometimes arg1, arg2, 
arg3 are passed.
How can i manage this?
