input: Write a function to print the multiplication table of a given number. The function should iterate over numbers from 1 to 10 and print the result of the multiplication for each iteration. If the given number is negative, the function should print a message saying that the input is invalid.
  assert print_multiplication_table(5)
  assert print_multiplication_table(10)
  assert print_multiplication_table(-3)
  assert print_multiplication_table(0)
  
  
output: def print_multiplication_table(number):
      if number < 0:
          print("The input is invalid.")
      else:
          for i in range(1, 11):
              print(f"{number} * {i} = {number * i}")
