input: Write a python function to get the size of an object using sys.getsizeof.
  assert size_of_object(10) == 28  # Note: The actual size may vary depending on the system.
  assert size_of_object("hello") == 54  # Note: The actual size may vary depending on the system.
  assert size_of_object([1, 2, 3]) == 80  # Note: The actual size may vary depending on the system.
output: def size_of_object(obj):
      import sys
      return sys.getsizeof(obj)
