  Project Description: Counting sheep...
  
  Consider an array/list of sheep where some sheep may be missing from their place.
  We need a function that counts the number of sheep present in the array (true means present).
  
  For example,
  
  [True,  True,  True,  False,
    True,  True,  True,  True ,
    True,  False, True,  False,
    True,  False, False, True ,
    True,  True,  True,  True ,
    False, False, True,  True]
  
  The correct answer would be 17.
  
  Hint: Don't forget to check for bad values like null/undefined

  def count_sheeps(sheep):
      return sheep.count(True)
