将字符串句子列表转换为单词

Question

我试图基本上采用包含句子的字符串列表,例如:

sentence = ['Here is an example of what I am working with', 'But I need to change the format', 'to something more useable']

并将其转换为以下内容:

word_list = ['Here', 'is', 'an', 'example', 'of', 'what', 'I', 'am',
'working', 'with', 'But', 'I', 'need', 'to', 'change', 'the format',
'to', 'something', 'more', 'useable']

我试过用这个:

for item in sentence:
    for word in item:
        word_list.append(word)

我认为它会占用每个字符串并将该字符串的每个项目附加到word_list,但输出的内容如下:

word_list = ['H', 'e', 'r', 'e', ' ', 'i', 's' .....etc]

我知道我犯了一个愚蠢的错误,但我无法弄清楚为什么,任何人都可以帮忙吗？

Answer 1

您需要str.split()将每个字符串拆分为单词:

word_list = [word for line in sentence for word in line.split()]

Answer 2

只是.split和.join:

word_list = ' '.join(sentence).split(' ')
