input: Write a function to generate a Python program that prints every number from 0 to 10, with each number multiplied by 2.
  
  assert multiply_by_two(0, 10) == '''for i in range(11):
   print(i*2)'''
  assert multiply_by_two(0, 5) == '''for i in range(6):
   print(i*2)'''
  assert multiply_by_two(0, 3) == '''for i in range(4):
   print(i*2)'''
  assert multiply_by_two(0, 1) == '''for i in range(2):
   print(i*2)'''
  assert multiply_by_two(0, 0) == '''for i in range(1):
   print(i*2)'''
output: def multiply_by_two(start, end):
      return f'''for i in range({end + 1}):
   print(i*2)'''
