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 each multiplication expression in the format 'number x multiplier = product'.
  def print_multiplication_table(num):
      for i in range(1, 11):
          print('{0} x {1} = {2}'.format(num, i, num*i))
  
  assert print_multiplication_table(5)
  assert print_multiplication_table(3)
  assert print_multiplication_table(7)
  assert print_multiplication_table(2)
  assert print_multiplication_table(9)
output: def print_multiplication_table(num):
      for i in range(1, 11):
          print('{0} x {1} = {2}'.format(num, i, num*i))
