I understand % as modulus, but i do not understand % as used below. What is its function here:

Question

def foo(first, second, third, *therest):
print("First: %s" % first)
print("Second: %s" % second)
print("Third: %s" % third)
print("And all the rest... %s" % list(therest))
---------------
I'm not referring to the "%s" (string), but the "% first" etc. in the code. I can't find any explanation of it in my searches

Answer 1

here % is not modulo operator :( . it is format. (and you miss commas inside print function.)

Answer 2

Thanks Yuri for your answer. The link is very helpful. This code is copied from an online course, so I cannot speak to any other errors.

Answer 3

always copy- paste to Code Playground to make sure it work as expected!
(maybe, the second % works as a comma).
