  # Enter a code

  d = {'Alice': [50, 61, 66], 'Bob': [80, 61, 66], 'Candy': [88, 75, 90]}

  
  

  m = 0

  for key in d.keys():

      m += 1

  print(m)

  
  

  n = 0

  for x in d:

      n = n + 1

      print(x) #打印出来看看

  print(n)

  
  

  y = 0

  for s in d.values():

      y += 1

      print(s)

  print(y)

  
  

  感觉可以
