input: Write a function to create a loop in Python that prints each item of a given list with a message. The function should take a list as input and print each item with the message "The item is: {}". If the given list is empty, the function should print nothing.
  assert loop_with_message(['A', 'B', 'C', 'D']) == None
  assert loop_with_message([]) == None
output: def loop_with_message(lst):
      for item in lst:
          print(f"The item is: {item}")
