input: Write a function to generate a multiplication table for numbers in a given range specified by start and end parameters. The table should print out the products of numbers within this range.
  
  def multiplication_table(start, end):
  	for x in range(start, end + 1):
  		for y in range(start, end + 1):
  			print(x * y, end = "  ")
  		print("\n")
  
  assert multiplication_table(5, 10)==None
  assert multiplication_table(1, 3)==None
  assert multiplication_table(2, 7)==None
  assert multiplication_table(0, 4)==None
  assert multiplication_table(-3, 3)==None
output: def multiplication_table(start, end):
  	for x in range(start, end + 1):
  		for y in range(start, end + 1):
  			print(x * y, end = "  ")
  		print("\n")
