'builtin_function_or_method' not iterable

Hey guys,

Got a bit of code here that looks like this:

def members(dict, list):
  inc_item = []
  for item in list:
    if item in dict.keys:
      inc_item.append(item)

  return len(inc_item)

Inputs are a dictionary and a list of keys looking to return the number of keys in the list that are included in the dictionary. When I try to check it i get the following: argument of type 'builtin_function_or_method' is not iterable.

Is there something that I'm missing? Or is my code just dumb?

Thanks

I figured it out:

dropped the ".keys" on line 4 and it works.

.keys is a method that's built into the dict type. Since it's a method, it has to be called, .keys(), and not just used directly like you were doing.

But, yes, you don't need the .keys() for this.
