Hi Abe First, I have reservations about the name lambda. But there's a lot of code out there that uses lambda, and I'd like that code to continue to run.
You wrote: > func = value[card.suit] if card not in wilds else wild_value with card I thought I'd try this, and variants, in the Python interpreter. I got # An expression. It's valid syntax, get run-time error. >>> value[card.suit] if card not in wilds else wild_value NameError: name 'card' is not defined # An expression. It's valid syntax. Its value is a function. No run-time error. >>> lambda card: value[card.suit] if card not in wilds else wild_value <function <lambda> at 0x7ff815e2bbf8> # If Python were enhanced, an valid expression whose value is a function. >>> value[card.suit] if card not in wilds else wild_value with card SyntaxError: invalid syntax My understanding is that you prefer >>> EXPRESSION with IDEN to >>> lambda IDEN: EXPRESSION How do you feel about this, as a means of defining an anonymous function? >>> with IDEN: EXPRESSION We can't adopt it, of course, because it's already valid syntax, but with semantics. >>> with wibble: ... wobble NameError: name 'wibble' is not defined Now for a trick question. Consider >>> fn = (lambda : EXPRESSION) This produces a function that has zero parameters. How would you write this, using 'with'. Would it be: >>> fn = (EXPRESSION with) I think this looks rather odd. -- Jonathan _______________________________________________ Python-ideas mailing list Python-ideas@python.org https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/
