# 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
dict = {'a':1, 'b':2, 'c':3, 'd':4}
list = ['a','b','v','d']
def members(dict,list):
counts = 0
for item in list:
if item in dict():
counts += 1
return counts
