counts.py 
# You can check for dictionary membership using the
# "key in dict" syntax from lists.

### Example
# my_dict = {'apples': 1, 'bananas': 2, 'coconuts': 3}
# my_list = ['apples', 'coconuts', 'grapes', 'strawberries']
# members(my_dict, my_list) => 2

:point_right: Here's a few hints:

  • you'll probably want a loop to iterate through the items in the list
  • for each list item, you'll want to test to see if it is "in" the dictionary
  • it it is, you'll increment a counter
  • after the loop is done, you can return the value in the counter

I'll bet you can do it now without an explicit spoiler.
