New submission from Jeremy <ucod...@gmail.com>:
A source of one or more backslash-escaped newlines, and one final newline, is not tokenized the same as a source where those lines are "manually joined". The source ``` \ \ \ ``` produces the tokens NEWLINE, ENDMARKER when piped to the tokenize module. Whereas the source ``` ``` produces the tokens NL, ENDMARKER. What I expect is to receive only one NL token from both sources. As per the documentation "Two or more physical lines may be joined into logical lines using backslash characters" ... "A logical line that contains only spaces, tabs, formfeeds and possibly a comment, is ignored (i.e., no NEWLINE token is generated)" And, because these logical lines are not being ignored, if there are spaces/tabs, INDENT and DEDENT tokens are also being unexpectedly produced. The source ``` \ ``` produces the tokens INDENT, NEWLINE, DEDENT, ENDMARKER. Whereas the source (with spaces) ``` ``` produces the tokens NL, ENDMARKER. ---------- components: Parser messages: 409811 nosy: lys.nikolaou, pablogsal, ucodery priority: normal severity: normal status: open title: backslash creating statement out of nothing versions: Python 3.10, Python 3.11, Python 3.6, Python 3.7, Python 3.8, Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue46274> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
