How do you replace regex end-of-line with string?

I have a for loop that produces a variable current_out_dir, sometimes the variable will have a /. at the end of the line (that is /.$) I want to replace /.$ with /$. Currently I have .replace('/.','/'), but this would replace hidden directories that start with . as well. e.g. /home/.log/file.txt

I've looked into re.sub() but I can't figure out how to apply it.

The question was about using regex, but I've come up with a more pythonic solution to the problem.

if os.path.split(current_out_dir)[1] == '.':
    current_out_dir = os.path.split(current_out_dir)[0]

/\.(?=$)

Try this.This should work for you.This uses a positive lookahead to assert end of string.

Dot will match any character not of newline character. So you need to escape the dot to match a literal dot.

re.sub(r'(?<=/)\.$', r'', string)
