# Write your count_first_letter function here:

def count_first_letter(names):
  first_letters = {}
  for key, value in names.items():
    if key[0] not in first_letters:
      first_letters[key[0]] = len(value)

# Uncomment these function calls to test your  function:
print(count_first_letter({"Stark": ["Ned", "Robb", "Sansa"], "Snow" : ["Jon"], "Lannister": ["Jaime", "Cersei", "Tywin"]}))
# should print {"S": 4, "L": 3}
print(count_first_letter({"Stark": ["Ned", "Robb", "Sansa"], "Snow" : ["Jon"], "Sannister": ["Jaime", "Cersei", "Tywin"]}))
# should print {"S": 7}
