Why do we need * in (*bar) in the code below?

Question

def foo(a,b,c):
print(a,b,c)

bar=(3,14,15)
foo(*bar)

Answer 1

its more like:

def foo(*bar):
for b in bar:
print(b, end=' ')

Input:
foo(1,3,5,7)
foo(2,4)

Output:
1 3 5 7
2 4

And for what happens when its not there, try it out and see

Answer 2

* allows you to pass an arbitrurary amount of arguments. The variable bar is usually: args (as in arguments)

Answer 3

Slick So what happens it it is not used here?
