How do i make a string of only one backslash? For example s = "\"

Question

I am working on a project and to make a new path I needed backslash as a string.

So far I've tried S = "\", but it didn't work.

This code snippet might help you to understand the situation.

dir_num = "1566510932"
reduced_base_directory = phosphogly_ws_len_path + r"\" + dir_num + r".result" + r"\" + dir_num + r".fas."

The *representation* of `"\\"` is `'\\'`, but it's still a single character: `len("\\") == 1`. — chepner, Aug 22 '19 at 22:49
The problem with `r"\"` is [documented](https://docs.python.org/3/reference/lexical_analysis.html#string-and-bytes-literals) (at the end of the linked section): "Specifically,*a raw literal cannot end in a single backslash* (since the backslash would escape the following quote character)." — chepner, Aug 22 '19 at 22:53
It is better to use forward slashes for a [Windows path in Python](https://stackoverflow.com/questions/2953834/) anyway. — Karl Knechtel, Aug 07 '22 at 04:31

You can give it an extra slash:

S="\\"

@DiptoPaulDip No, it doesn't. It produces a string whose string *representation* contains a double backslash. – chepner Aug 22 '19 at 22:50
