New submission from Terry J. Reedy: Functional Programming HowTo, near the end, has a section Small functions and the lambda expression http://docs.python.org/3/howto/functional.html#small-functions-and-the-lambda-expression
To illustrate, it starts with adder = lambda x, y: x+y print_assign = lambda name, value: name + '=' + str(value) which are now proscribed by PEP 8. "Always use a def statement instead of an assignment statement that binds a lambda expression directly to a name." The text goes on to give the def equivalents and to discourage lambdas. "Which alternative is preferable? That’s a style question; my usual course is to avoid using lambda." But I think the section should instead start with lambda examples that would be acceptable in the stdlib. ---------- messages: 194301 nosy: akuchling, terry.reedy priority: normal severity: normal stage: needs patch status: open title: FP Howto and the PEP 8 lambda guildline versions: Python 2.7, Python 3.3, Python 3.4 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue18648> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
