Hi INADA Naoki, (Sorry, I am unsure if INADA or Naoki is your first name...) While I am very much in favour of everything working "out of the box", an issue is that we don't have control over external code (be it Python extensions or external processes invoked from Python). And that code will on

Re: [Python-ideas] Python reviewed

for range(1,1): means executing once to me. The indexing/slicing approach was designed for indexing and slicing. Then it made sense to have range() match. But range() is not part of the for construction. It is a convenience function for providing an iterable of integers. And you are welcome to wr

Hi, I also implemented my PEP 540, you can now test it! Use the latest patch attached to: http://bugs.python.org/issue29240 I made multiple changes since the first version of my PEP: * The UTF-8 Strict mode now only uses strict for inputs and outputs: it keeps surrogateescape for operating

[Python-ideas] Things that won't change (proposed PEP)

I have a proposal for an Informational PEP that lists things which will not change in Python. If accepted, it could be linked to from the signup page for the mailing list, and be the one obvious place to point newcomers to if they propose the same old cliches. Thoughts? * * * * *

I think this is a fine idea, but I also think we could use a more verbose FAC: Frequently Asked Criticisms Some of the same things, but it would focus on the "why" of many of the issues. Many of the things people (newbies, mostly) complain about are simply taste, or legacy that isn't worth chang

I feel I have to respond to this one. More than half of what I suggested could have and should be implemented. In particular the truthiness of non-boolean data and the lack of a reasonable SQL syntax. Several other points have been discussed endlessly on the internet but without a satisfactor

Re: [Python-ideas] PEP 540: Add a new UTF-8 mode

It seems to me that having a C locale can mean two things: 1) It really is meant to be ASCII 2) It's mis-configured (or un-configured), meaning the system encoding is unknown. if (2) then utf-8 is a fine default. if (2), then there are two options: 1) Everything on the sytsem really is ASCII -
