Why doesn't this code work on the Membership Challenge within Python Collections?

def members{dict, keys}:
  return len(members.keys())

I've changed the format of your question to make the code clearer

+1 with what Ryan said above. Also, you're using {} instead of () when writing your function. It should be:

def members(dict, keys):
    #rest of the code

Also "dict" is a reserved keyword to manipulate dictionaries, if I am not mistaken.

Some pseudo code that could help you:

def members(dict1, keys):
  #set a counter to 0
  count = 0
  for e in keys:
    #check if that element is in the dictionary
    #increment the counter
  return count

You're supposed to be counting the unique keys in the dictionary. I would suggest keeping track of how many unique keys there are in the dictionary, by looping through the dictionary. Good luck!

I had to use a for loop and an if statement.
