在一行文本中添加行返回，但不要打断单词

Question

我有一个长字符串，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。 除非我不想将一个单词分成两半，所以如果它分成22个字母，那很好。 有谁知道智能解决方案吗？

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...']
