I don\'t understand how raw string literals work. I know that when using r it ignores all specials, like when doing \\n it treats it as \\n and not

    In a raw literal the backslash will escape the quote character that is defining the string.

    String quotes can be escaped with a backslash, but the backslash remains in the string; for example, r"\"" is a valid string literal consisting of two characters: a backslash and a double quote; r"\" is not a valid string literal (even a raw string cannot end in an odd number of backslashes). Specifically, a raw string 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 string, not as a line continuation.

    From the docs
