No it doesn't. You are printing things not returning something.

and combine_list is the most stupidest function you could write
in Python, as it is built-in with the name 'zip'.

  >>> name = ['Alice', 'Bob', 'Cathy', 'Dan', 'Ed', 'Frank', 'Gary', 
'Helen', 'Irene', 'Jack', 'Kelly', 'Larry']
  >>> age = [20, 21, 18, 18, 19, 20, 20, 19, 19, 19, 22, 19]
  >>> dic = dict(zip(name,age))
  >>> def people(age):
  ...     ''' How stupid it is to write three line for a one-line
              function'''
  ...     return [name for name in dic if dic[name]==age]
  ...
  >>> people(20)
  ['Gary', 'Alice', 'Frank']

Sorry for having being rude, but :
1. you shouldn't post raw homework in any kind of public group
(aren't you supposed to learn something by yourself ?)
2. your teacher is a nut.
