TypeError：“ bool”类型的参数不可迭代

Question

say I have a dictionary ie

dict = {'tommy' = '[[], []]'}

when I run the code below, it gives the error: argument of type bool is not iterable . I'm really stuck on this and would appreciate a solution. The code takes two inputs, the dict and a user. It's supposed to check if user is in dict - if it is, return the first element in the value. otherwise, return None.

def get_stuff(dict, user):
    if user in dict:
         return dict[user][0]
    return None

Answer 1

problem is

dict = {'tommy' = '[[], []]'}

you have to give it as

dict = {'tommy' = [[], []]}

dict with list as element
