Check the number of parameters passed in Python function

Question

I\'m new in Python and wants to know if there is a simple way to get amount of passed parameters in Python function.

a(1, 2, 3) ==>3
a(1, 2) ==>2
         


        

Answer 1

you could also change the input for your function to a list, so to have a function:

a(your_list)

then to know how many arguments have been passed to the function, you could simply do:

print len(your_list)

However, this means that you change the input type for your function, from many input variables to only one, the list(which can have a variable number of elements).
