Special Characters in string literals
提问by Illyduss
I am making a set in Python to house all the symbols on my keyboard, but obviously a few pose some issues. Is there a way to get them all in there without encountering problems?
我正在用 Python 制作一个集合来容纳我键盘上的所有符号，但显然有一些会带来一些问题。有没有办法让他们都在那里而不会遇到问题？
Here is my set:
这是我的套餐：
symbols = {`,~,!,@,#,$,%,^,&,*,(,),_,-,+,=,{,[,},},|,\,:,;,",',<,,,>,.,?,/}
To get around commenting out most of it, since in Python #is to comment, I enclosed everything like so:
为了避免注释掉大部分内容，因为在 Python 中#是注释，所以我将所有内容都包含在内：
symbols = {'`','~','!','@','#','$','%','^','&','*','(',')','_','-','+','=','{','[','}','}','|','\',':',';','"',''','<',',','>','.','?','/'}
Which works for that character, but now I can already see an issue when I come across the 'and \. Is there a better way to make this set?
这适用于该角色，但现在当我遇到'和时，我已经可以看到一个问题\。有没有更好的方法来制作这个套装？

You can fix the backslash by escaping it and 'can be fixed by putting it in double quotes:
您可以通过转义反斜杠来修复它，并且'可以通过将其放在双引号中来修复它：
symbols = {..., '\', ... "'", ...}
But typing all this out is pretty tedious. Why not just use string.punctuationinstead:
但是把所有这些都打出来是很乏味的。为什么不直接使用string.punctuation：
>>> from string import punctuation
>>> set(punctuation)
{'~', ':', "'", '+', '[', '\', '@', '^', '{', '%', '(', '-', '"', '*', '|', ',', '&', '<', '`', '}', '.', '_', '=', ']', '!', '>', ';', '?', '#', '$', ')', '/'}
>>>
