anomalous-backslash-in-string / W1401#
Anomalous backslash in string: '%s'. String constant might be missing an r prefix.
Used when a backslash is in a literal string but not as an escape.
string = "\z" # [anomalous-backslash-in-string]
string = "\\z"
string = "\t"
string = r"\z"
\z is same as
\\z because there's no escape sequence for
z. But it is not clear
for the reader of the code.
Created by the string checker.
