input: Write a function to print out all the odd numbers from a given range [start, end]. Only include the numbers that are odd. The function should take two inputs, start and end, which represent the range in which the function will search for odd numbers. The function should not return any value; it should only print the odd numbers directly.
  assert print_odd_numbers(1, 10)==None
  assert print_odd_numbers(2, 20)==None
output: def print_odd_numbers(start, end):
      for num in range(start, end + 1):
          if num % 2 != 0:
              print(num)
