Python编号中的下划线 [英] Underscores in Python numbers
问题描述
我试图找到一个关于添加在Python中数字内部可选下划线的可能性的讨论。这是一个受欢迎的选项
可在几个竞争中获得。脚本langauges，我很想用Python看看
。
例子：
1_234_567
0xdead_beef
3.141_592
如果有人能找到关于此主题的先前
讨论的指针，或者添加，我将不胜感激它是一个Python功能愿望清单。

I tried finding a discussion around adding the possibility to have
optional underscores inside numbers in Python. This is a popular option
available in several "competing" scripting langauges, that I would love
to see in Python.
Examples:
1_234_567
0xdead_beef
3.141_592
Would appreciate if someone could find a pointer to a previous
discussion on this topic, or add it to a Python-feature-wishlist.

我不知道_s的用途是什么，但我猜他们用作
分隔符（。或，，依赖于你来自哪里）。我觉得_s
对我来说看起来很难看，而且，下划线看起来更像是空格而不是
分隔符。
I''m not sure what the _s are for, but I''m guessing they serve as
separators ("." or "," depending on where you''re from). I think the _s
look ugly to me, besides, underscores look more like spaces than
separators.

我''我从来没有在Python中需要它们，但是我经常希望它们在C中使用
。对于二进制数字，它们是0b（0 | 1）*，它们甚至会是
更有用。
当然，我在C中编写了比Python多_far_的代码。但是我已经看到了足够的错误，有人写了1200000，当他们意味着
12000000时，我认为能够指定12_000_000很有价值。 />
问候，

变化是不可避免的，进步不是。
I''ve never needed them in Python, but I''ve very often wished for them
in C. Along with 0b(0|1)* for binary numbers, where they''d be even
more useful.
Of course, I write _far_ more code in C than Python. But I''ve seen
enough bugs of the sort where someone wrote 1200000 when they meant
12000000, that I see great value in being able to specify 12_000_000.
