how to create a raw string when it's last character is a `\` in python

Question

As we all know,we can create a string like this:

str1 = r"\abc\test"

But if I want put the \ in the end of a string like:

str2 = r"\abc\test\"

A syntax error occurs ! I have found an answer,but it's in JavaScript. `String.raw` when last character is `\` So,How to deal this in python

escape the `'\'` with the escape character which is `'\'`. so it will look like this `'\\'` — Ma0, Oct 17 '17 at 12:27
@Ev.Kounis Then you'll have 2 backslashes at the end of your string. — Aran-Fey, Oct 17 '17 at 12:29
Interestingly enough, the updated duplicate helps explain this raw string behaviour. — idjaw, Oct 17 '17 at 12:35
Append a throwaway character, then slice it out `r'\dontcare'[0]` — smci, Sep 09 '18 at 23:33

You can concat another normal string:

>>> r'\abc\test' + '\\'
'\\abc\\test\\'

duplicated Why can't Python's raw string literals end with a single backslash?

https://docs.python.org/3/reference/lexical_analysis.html

Specifically, a raw literal cannot end in a single backslash (since the backslash would escape the following quote character). Note also that a single backslash followed by a newline is interpreted as those two characters as part of the literal, not as a line continuation.
