python-idle - 在 Python IDLE 中换行

Question

我正在写的字符串很长。为了更容易阅读，我想将文本换成多行。这是怎么做的。我之前已阅读说明，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的输入，您可以输入多行字符串，然后删除换行符。但是，如果您希望行以逗号和句点后的空格结尾，您将看不到它们，如果您从代码中去除行尾空格，它们就会消失。（这是 CPython 标准库代码所必需的。）

另一种方法是使用 Python 的字符串文字连接功能。空格由行尾引号保护，并且可以添加注释。（有关另一个示例，请参见链接。）

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.
