如何在Python中使用for循环创建列表列表？

Question

以下是我当前的列表：

wordOccur = ['tears', 1, 'go', 1, 'i', 4, 'you', 7, 'love', 2, 'when', 3]

我就是这样创建它的：

    wordOccur = []

    for x in keywords:

            count = words.count(x)

            wordOccur.append(x)

            wordOccur.append(count)

词语指的是字符串列表。每根弦都是一首诗中的单数词

我如何制作wordOccur = [['tears', 1], ['go', 1],[ 'i', 4],[ 'you', 7],[ 'love', 2],[ 'when', 3]]

Answer 1

您可以更改此代码

wordOccur = []

for x in keywords:
  count = words.count(x)
  wordOccur.append(x)
  wordOccur.append(count)

将其转换为此代码

wordOccur = [[word, keywords.count(word)] for word in keywords]
