What does *num stands for or what it does in given code

Question

a=3
def sumofnum(*num):
return sum(num)
print(sumofnum(a,a**a,a*4))

Answer 1

(*num) is kind of optional parameter...
it takes any number of arguments passed to the function....
that code will output :- 42
as it will take all three arguments passed and will sum it up...
a+a**a+a*4 = 3+3**3+3*4 = 3+27+12 = 42

Consider 1 more eg.:-
a=3
def fun(n,*num) :
return something
print (fun(1,2,3,4,5))
"""now here n is mandatory parameter & num is optional so 1 will be passed to n & rest will be passed to num...
i hope this helps 😊"""
