This reminds me a bit of complaints that the parser does not do what you want when you do not supply parentheses in an expression like:
5 * 4 + 3 In many and maybe most languages it is seen as (5*4)+3 UNLESS you tell it you want 5*(4+3). There are precedence and associativity rules. Of course the computer might guess you meant the latter or could refuse to do it and offer you a choice before calculating it. Or the language may insist on parentheses always so you would need to also say ((5*4)+3) with no default behavior. The golden rule remains. If there is more than one way something can be done, then either the programmer must make the choice explicit OR the documentation must very clearly warn which path was chosen and perhaps point to ways to do other choices. Some people take more complex (but not Complex) arithmetic than the above and break it up into quite a few simple parts like: temp1 = 4 + 3 result = 5 + temp1 Of course, the latter can be hard to read and understand for some people, and some (others?) find fully parenthesized versions hard. But having precedence rules and also allowing the other methods, should work fine for a good segment of people except perhaps the ones who like Reverse Polish Notation and insist on 5 4 3 + * instead. -----Original Message----- From: Python-list <python-list-bounces+avi.e.gross=gmail....@python.org> On Behalf Of aapost Sent: Thursday, April 13, 2023 12:28 PM To: python-list@python.org Subject: Re: Weak Type Ability for Python On 4/12/23 04:03, Ali Mohseni Roodbari wrote: > On 4/13/23 07:50, Stefan Ram wrote: > If tomorrow Python would allow "string+int" and "int+string" > in the sense of "string+str(int)" and "str(int)+string", > what harm would be there? > > But for now, I think a typical approach would be to just use "str", > i.e., "string+str(int)" and "str(int)+string". I agree with Py Zen rule 2 in this case: Explicit is better than implicit. I hate when things try to guess what I am doing...
