1,451 Pointsreturning vs. printing a value in functions in Python
When I print a parameter in a function, I receive a strange None at the end. What's reason? Example:
def packer (*args):
for val in args:
print (val)
print (packer('i','love','you'))
Result looks like this:
i
love
you
None

Treehouse TeacherHi Mark Maksi ! You are getting the None because you are also printing your function call print(packer('i','love','you')). If you just call the function on its own you won't see the None like this: packer('i','love','you'). This is because you've told Python to print the function too which typically prints whatever is returned from a function but you aren't returning anything so there is nothing to print, or None.
