[Python-Dev] Adding test.support.safe_rmpath()

Hello, after discovering os.makedirs() has no unit-tests ( https://bugs.python.org/issue35982) I was thinking about working on a PR to increase the test coverage of fs-related os.* functions. In order to do so I think it would be useful to add a convenience function to "just delete something if it

Bikeshedding: I suggest to remove "safe_" from the name, it's hard to guarantee that removal is "safe", especially on Windows where a removal can be blocked for many reasons. Victor Le mer. 13 févr. 2019 à 13:28, Giampaolo Rodola' a écrit : > > > Hello, > after discovering os.makedirs() has no

Re: [Python-Dev] Another update for PEP 394 -- The "python" Command on Unix-Like Systems

Hi, I'm a (strong) supporter of providing a "python" command which would be the latest Python version! As php does nowadays (after previous issues with "php4" vs "php5".) I don't recall that perl had "perl4" vs "perl5", the command was always "perl", no? Same for Ruby: it was still "ruby" after

Some more context about Petr's change, Fedora, RHEL and Red Hat. At the latest Language Summit (2018), Petr detailed the state of the migration to Python 3 and how Python 2 is and will be handled at Red Hat; "Linux distributions and Python 2" talk with Matthias Klose (who works on Debian/Ubuntu):

Oops. That isn't the TOTAL microseconds, but just the microseconds portion. Sorry for the confusion. On Wed, Feb 13, 2019 at 9:23 PM Henry Chen wrote: > Looks like timedelta has a microseconds property. Would this work for your > needs? > > In [12]: d > Out[12]: datetime.timedelta(0, 3, 398407)

Looks like timedelta has a microseconds property. Would this work for your needs? In [12]: d Out[12]: datetime.timedelta(0, 3, 398407) In [13]: d.microseconds Out[13]: 398407 On Wed, Feb 13, 2019 at 9:08 PM Richard Belleville via Python-Dev < python-dev@python.org> wrote: > In a recent code

In a recent code review, the following snippet was called out as reinventing the wheel: _MICROSECONDS_PER_SECOND = 100 def _timedelta_to_microseconds(delta): return int(delta.total_seconds() * _MICROSECONDS_PER_SECOND) The reviewer thought that there must already exist a standard
