input: Write a function to create a python program that takes in the size of a jagged array and prints it without any values. The function should initialize a jagged array of the given size with empty arrays, and then print the array.
  
  def print_jagged_array(array_size):
      array = [None] * array_size
      for i in range(array_size):
          array[i] = []
      print(array)
      
  if __name__ == "__main__":
      array_size = 4
      print_jagged_array(array_size)
  
  assert print_jagged_array(4)==None
  assert print_jagged_array(3)==None
  assert print_jagged_array(0)==None
  assert print_jagged_array(1)==None
output: def print_jagged_array(array_size):
      array = [[] for _ in range(array_size)]
      print(array)
