input: Write a function to generate a multiplication table with numbers within a specified range given two parameters, start and end. The function should print the product of each number within the range with every other number in that same range.
  assert multiplication_table(5, 10)
  assert multiplication_table(1, 5)
  assert multiplication_table(3, 6)
  assert multiplication_table(7, 9)
  assert multiplication_table(2, 4)
output: def multiplication_table(start, end):
      for i in range(start, end + 1):
          for j in range(start, end + 1):
              print(f"{i} * {j} = {i * j}")
