Issue 27947: Trailing backslash in raw string format causes EOL (original) (raw)

Thanks for comment. Here I got my answer from string docs.

Even in a raw literal, quotes can be escaped with a backslash, but the backslash remains in the result; 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 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.
