Python将“\"转换为“\\" [英] Python converting '\' to '\\'

问题描述

我正在编写一个程序来对输入字符串(歌曲名称)的列表进行排序.这些歌曲名包含像 $\lambda$ 这样的乳胶字符，我想要而是像 'lambda' 一样排序，så 我正在使用应用的能力排序期间每个元素的函数.像这样:

I am writing a program to sort a list fo input strings (song names). Those songnames contains latex chars like $\lambda$, which i want to get sorted like 'lambda' instead, så i'm using a the ability to apply a function to each element during sort. like this:

# -*- coding: UTF8 -*-
def conv( inp ):
    if inp == '$\lambda$':
        return 'lambda'
    else:
        return inp

mlist = []
mlist.append('martin')
mlist.append('jenny')
mlist.append('åse')
mlist.append('$\lambda$')
mlist.append('lambda')
mlist.append('\her')
print (mlist)
mlist = sorted(mlist, key=conv(str.lower))
print (mlist)

但出于某种原因，当我附加 lambda 符号或 \her 时，它会将其转换为 \\her 或 $\\lambda$，我可以防止这种情况发生吗?

But for some reason, when i append the lambda sign or \her it converts it to \\her or $\\lambda$, can i prevent this?

不，不是.您看到的是表示，为了清晰起见，它总是将单独的反斜杠加倍.如果你打印实际的字符串，你会发现它们没问题.

No it doesn't. What you're seeing is the representation, which always doubles solo backslashes for clarity. If you print the actual strings instead you'll see that they're fine.
