Welcome to the python list. Thanks for posting a question.
If you were hoping for one of us to write the program for you ... well
that's not what we do on this list.
Please post the code you have so far and tell us exactly where you need
help.
Also tell us what version of Python, what OS, and what you use to write
and run Python programs.
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
You didn't write a function which return a result, so you have no
result.
