python-idle - 在 Python IDLE 中包装文本

Question

我写的字符串很长。为了便于阅读，我想将文本换行到多行。这是怎么做到的。我以前看过说明，但现在找不到了。

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，如果您希望行在逗号和句号之后以空格结尾，您将看不到它们，并且如果您从代码中去除行结尾的空白，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特征。空白由行尾引号保护，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.
