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={} def combine_lists(name,age): for i in range(len(name)): dic[name[i]]= age[i] combine_lists(name,age) print dic def people(age): people=lambda age: [name for name in dic if dic[name]==age] people(20) this is the code i have so far(with the help of the first post ;p). i understand how a function and a dictionary works and what I'm asked to find. but i don't get the lambda age part. and this code doesn't give me any result -- https://mail.python.org/mailman/listinfo/python-list
