counts.py

Write a function named members that takes two arguments, a dictionary and a list of keys. Return a count of how many of the keys are in the dictionary.

my code:

def members(my_dict, my_keys): count = 0 for key in my_dict: if key in my_keys: count =+ 1 return count

error: Bummer! Expected 2, got 1.

def members(my_dict, my_keys): 
    count = 0 
    for key in my_dict: 
        if key in my_keys: 
                count += 1 
    return count

you had the "+=" backwards
