[New-bugs-announce] [issue38915] 'r[/]*', str, re.MULTILINE | re.DOTALL Won't match // in a string in Python3.6.8

[Yan]

New submission from Yan <yanioaioan at gmail.com>:

str="//"
matches = re.finditer('r[/]*', str, re.MULTILINE | re.DOTALL)
for match in matches:
    print(match.group(0))

The above will match double forward slash in Python2.7.15  but NOT in Python3.6.8.
