not not working looping through a dictionary

[buran]

on line 10 you want to iterate over the list peoples, not over the keys of the dict.

peoples = ['jen', 'sarah', 'edward', 'phil', 'jeff', 'cara', 'ben', 'adam', 'larry']
favorite_languages = {
    'jen' : 'python',
    'sarah' : 'c',
    'edward' : 'ruby',
    'phil' : 'python',
    'jeff' : 'python',
    'cara' : 'none',
    }
for person in peoples:
    if person in favorite_languages:
        print("Thanks {} for taking the survey.".format(person.title()))
    else:
        print("{}, Please take the survey.".format(person.title()))
