Python 中的文本换行

Question

我写的字符串很长。为了更容易阅读，我想将文本换行为多行。这是怎么做到的？

Answer 1

[这个答案一般适用于 Python，并不特定于 IDLE。]

对于输入没有嵌入换行符的长字符串，您可以输入多行字符串，然后删除换行符。但是，如果您希望行在逗号和句点之后以空格结尾，则您将看不到它们，并且如果您从代码中删除行结束空格，它们也会消失。 （这是 CPython stdlib 代码所必需的。）

另一种方法是使用 Python 的 字符串文字连接 功能。空格由行结束引号保护，并且可以添加注释。 （请参阅另一个示例的链接。）

stories = {
    'John' : "One day John went to the store to buy a game.  "  # the lead
        "The name of the game was Super Blaster.  "  # the hint
        "On the way to the store, John was blasted by a purple ray.  "
        "The ray of purple light, mixed with super neutrinos, "
        "came from a alien spaceship hovering above."
    }

import textwrap
print('\n'.join(textwrap.wrap(stories['John'])))

# prints

One day John went to the store to buy a game.  The name of the game
was Super Blaster.  On the way to the store, John was blasted by a
purple ray.  The ray of purple light, mixed with super neutrinos, came
from a alien spaceship hovering above.
