在Python IDLE中包装文本

Question

我写的字符串很长。为了便于阅读，我想将文本包装成多行。怎么做我之前已阅读过说明，但现在无法找到它们。

Answer 1

[这个答案一般适用于Python，并不特定于IDLE。]

对于没有嵌入换行符的长字符串输入，您可以输入多行字符串，然后删除换行符。但是如果你想在逗号和句点之后用行结尾的行，你将看不到它们，如果你从代码中删除行结尾的空格，它们就会消失。 （这是CPython stdlib代码所必需的。）

另一种方法是使用Python的string literal concatenation功能。白色空间由行尾引号保护，可以添加注释。 （有关其他示例，请参阅链接。）

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.
