'''
Problem 3

Write a function called names, which takes a list of
strings as a parameter. The strings are intended to represent
a person's first and last name (with a blank in between).
Assume the last names are unique. The function should return a
dictionary (dict) whose keys are the people's last names, and
whose values are their first names.

For example:
>>> dictionary = names([ 'Ljubomir Perkovic', \
'Amber Settle', 'Steve Jost'])
>>> dictionary['Settle']
'Amber'
>>> dictionary['Jost']
'Steve'
>>> dictionary['Jost']
'Steve'

def names(list_of_names):
answer = { } # an empty dictionary
for name in list_of_names:
pass # replace
return answer

Answer 1

def names(list_of_names):
    answer = { } # an empty dictionary
    for name in list_of_names:
        lst = name.split(" ")
        answer[lst[1]] = lst[0]
    return answer

# Testing
dictionary = names([ 'Ljubomir Perkovic', 'Amber Settle', 'Steve Jost'])
print(dictionary['Settle'])
print(dictionary['Jost'])
print(dictionary['Jost'])
