New submission from Terry J. Reedy: [0. On mailing lists, 'lambda expression' is used rather than 'lambda form'. Docs use both. Consistency across docs is a broader issue than this one. So leave title alone for this one.]
1. (first sentence) "By popular demand, a few features commonly found in functional programming languages like Lisp have been added to Python." (in early Python 1!) I think this should just be deleted. See 4. below as a replacement. 2. " With the lambda keyword, small anonymous functions can be created." Change to "Small anonymous functions can be created with the lambda keyword." 3. change "Here’s a function that returns" to "This function returns" 3.5 add a sentence about the different between def and lambda (the name attribute. 4. Add sentences about the purposes of lambda. Add an example that illustrates passing functions. >>> pairs = [(1, 'one'), (2, 'two'), (3, 'three'), (4, 'four')] >>> pairs.sort(key=lambda pair: pair[1]) >>> pairs [(4, 'four'), (1, 'one'), (3, 'three'), (2, 'two')] ---------- assignee: docs@python components: Documentation files: tut-lambda.diff keywords: patch messages: 194296 nosy: docs@python, terry.reedy priority: normal severity: normal stage: patch review status: open title: Improve tutorial entry on 'Lambda Forms'. type: behavior versions: Python 2.7, Python 3.3, Python 3.4 Added file: http://bugs.python.org/file31142/tut-lambda.diff _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue18646> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
