Arguments are evaluated first and then the results are passed to the function. That's true throughout the language. In this instance, you can use \g<1> in the replacement string to refer to group 1: re.sub(r'([a-z]+)', fr"\g<1>{REPLACEMENT}", 'something') ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue41885> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
