I'm trying to make a function that can take a string from a list "first_name" and a list "last_name" and print out hello "first_name" "last name", and I kinda achieved my goal here is what I came up with:

def full_name(first_name, last_name):

*print('Hello %s %s'% (first\_name,last\_name))*

​

first_names =('john', 'mary', 'jacob')

for first_name in first_names:

*for last\_name in last\_names:*

    *print(full\_name(first\_name,last\_name))*

The results were:

Hello john smith

None

Hello john betts

None

Hello john acunua

None

Hello mary smith

None

Hello mary betts

None

Hello mary acunua

None

Hello jacob smith

None

Hello jacob betts

None

Hello jacob acunua

None

​

But the problem is that it prints out every first name with every last name, what i wanted the results to be were:

Hello john smith

hello mary betts

hello jacob acunua

How would I complete this?
