New submission from sco1 <sco1....@gmail.com>:
Came across this riddle today: >>> [0x_for x in (1, 2, 3)] [15] Initially I thought this was related to PEP 515 but the unexpected behavior extends to simpler examples as well, such as: >>> x = 5 >>> 123or x 123 >>> 123and x 5 I'm not familiar enough with C to understand why this is being parsed/tokenized this way, but this seems like it should instead be a SyntaxError. This appears to be fairly old behavior, as the non-underscored version works back to at least 2.7. And a bonus: >>> 0x1decade or more 31378142 ---------- messages: 390981 nosy: sco1 priority: normal severity: normal status: open title: Unexpected Parsing of Numeric Literals Concatenated with Boolean Operators type: behavior versions: Python 3.10, Python 3.7, Python 3.8, Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue43833> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
