input: Write a python function to print numbers from 1 to 100, but for multiples of 3 print "Fizz" instead, for multiples of 5 print "Buzz", and for multiples of both 3 and 5 print "FizzBuzz".
  assert fizzbuzz()[2] == "Fizz"
  assert fizzbuzz()[4] == "Buzz"
  assert fizzbuzz()[14] == "FizzBuzz"
  assert fizzbuzz()[0] == 1
output: def fizzbuzz():
      result = []
      for i in range(1, 101):
          if i % 3 == 0 and i % 5 == 0:
              result.append("FizzBuzz")
          elif i % 3 == 0:
              result.append("Fizz")
          elif i % 5 == 0:
              result.append("Buzz")
          else:
              result.append(i)
      return result
