Python 逆字母顺序

我有这个输出：[(3, 'one'), (2, 'was'), (2, 'two'), (1, 'too'), (1, 'racehorse'), (1, 'a')]

我需要将具有相同编号的元组按相反的字母顺序放置在列表中。这是我的代码：

`def top5_words(text):
  split_text = text.split()
  tally = {}
  for word in split_text:
    if word in tally:
      tally[word] += 1
    else:
      tally[word] = 1
  vals = []
  for key, val in tally.items():
    vals.append((val, key))
  reverse_vals = sorted(vals, reverse = True)
  return reverse_vals`

我输入的文字是： 一一是赛马 二二也是一

您可以使用list.sort与相反的论点：

>>> l = [(3, 'one'), (2, 'was'), (2, 'two'), (1, 'too'), (1, 'racehorse'), (1, 'a')]
>>> l.sort(key=lambda x: x[1], reverse=True)
>>> l.sort(key=lambda x: x[0])
>>> l
[(1, 'too'), (1, 'racehorse'), (1, 'a'), (2, 'was'), (2, 'two'), (3, 'one')]
