input: Write a python function to return a multiplication table of a given number as a list of strings.
  assert multiplication_table(6) == [' 6 X  1 =  6', ' 6 X  2 = 12', ' 6 X  3 = 18', ' 6 X  4 = 24', ' 6 X  5 = 30', ' 6 X  6 = 36', ' 6 X  7 = 42', ' 6 X  8 = 48', ' 6 X  9 = 54', ' 6 X 10 = 60']
  assert multiplication_table(3) == [' 3 X  1 =  3', ' 3 X  2 =  6', ' 3 X  3 =  9', ' 3 X  4 = 12', ' 3 X  5 = 15', ' 3 X  6 = 18', ' 3 X  7 = 21', ' 3 X  8 = 24', ' 3 X  9 = 27', ' 3 X 10 = 30']
output: def multiplication_table(number):
      return [f'{number:2} X {i:2} = {number * i:2}' for i in range(1, 11)]
