New submission from purificant <keilo.at+python.bug.trac...@gmail.com>:
A call to re.sub() returns different results in Python 3.7 compared to versions 3.6 / 3.5 and 2.7 Example behavior in 2.7 / 3.5 and 3.6: >>> re.sub(r'(([^/]*)(/.*)?)', r'\2.zip/\1/', 'example') 'example.zip/example/' Example in 3.7.0 and 3.7.1rc2: >>> re.sub(r'(([^/]*)(/.*)?)', r'\2.zip/\1/', 'example') 'example.zip/example/.zip//' As you can see the returned string is different for the same regex. re.subn() confirms that 2 replacements are made instead of 1. Is it intended to have different behaviour in 3.7+ or is this a bug?
