python - 在文本 block 中添加换行，但不要打断单词

Question

我有一个很长的字符串，例如:

mystring = 'It was the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness...'''

我想每 20 个字母插入一个换行符。除了我不想把一个词分成两半，所以如果它分成 22 个字母，那很好。有谁知道对此的智能解决方案？

Answer 1

使用textwrap :

>>> mystring = 'It was the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness...'''
>>> import textwrap
>>> textwrap.wrap(mystring, width=20)
['It was the best of', 'times, it was the', 'worst of times, it', 'was the age of', 'wisdom, it was the', 'age of', 'foolishness...']
