[issue21283] A escape character is used when a REGEXP is an argument of strip string function
Tito Bouzout added the comment: Thanks guys for the information! Is still weird to me that the escape character is used, but well ! Will remember this bug.

[issue21283] A escape character is used when a REGEXP is an argument of strip string function
New submission from Tito Bouzout: Hello! I got a report that the character \ was removed from a string using the following code \\server\path\to.strip(r'\'') At first insight, looks like a bug, because I don't expect the use of the escape character at all. Then I noticed, that our mistake there is that the strip argument should be a string not a REGEXP. Kinda weird to read, and I've no idea if this is expected behaviour in Python, as I'm relatively very new. So just informing, Kind regards, -- Tito -- components: Regular Expressions messages: 216687 nosy: Tito.Bouzout, ezio.melotti, mrabarnett priority: normal severity: normal status: open title: A escape character is used when a REGEXP is an argument of strip string function type: behavior versions: Python 3.3 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue21283 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Matthew Barnett added the comment: The argument isn't a regex, it's a raw string literal consisting of the characters (quote), \ (backslash), ' (apostrophe), (less than) and (greater than). -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue21283 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Eric V. Smith added the comment: In addition, you probably want \\server\path\to to be a raw string, too. That way, the backslashes are not given special meaning. Notice the difference in output between these two: \\server\path\to.strip(r'\'') 'server\\path\to' r\\server\path\to.strip(r'\'') 'server\\path\\to' In the first one, '\t' is being treated as a tab character, in the second one you see a backslash followed by a 't'. My rule of thumb is: any time you have a string with a filename containing backslashes, you want it to be a raw string. -- components: -Regular Expressions nosy: +eric.smith resolution: - not a bug stage: - committed/rejected status: open - closed ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue21283 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
