I just installed and ran the pep8 Python style guide checker. I get a few errors and warnings. One of them is W291 trailing whitespace. My question is, how do I in IDLE search for line breaks (or tab indentations for that matter). I tried ctrl+f using the Regular expression option and searching for \n, but that doesn't work. What am I doing wrong?
Kindly delete this question, if it doesn't belong on stackoverflow, as it is not a programming question as such. Thanks.
After giving it a try, the regex \s+$
does work.
explanation: \s
matches any single whitespace character. +
makes it match a series of whitespace characters. $
matches the end of the line. So, we're matching a series of whitespace characters immediately before the end of the line.
