[issue38065] Document the datetime capsule API
by Paul Ganssle Sept. 9, 2019

Sept. 9, 2019

New submission from Paul Ganssle <p.ganssle(a)gmail.com>: The datetime module has a capsule API, which is very useful for other languages' bindings, but the C API documentation for datetime only covers the C macros: https://docs.python.org/3/c-api/datetime.html The current extent of the documentation is that everyone who wants to bind to the C API (PyO3, Cython, pypy, etc), you need to just read the struct definition ( https://github.com/python/cpython/blob/master/Include/datetime.h#… [View More]

[issue38058] Tutorial: 4.2. for Statements
by Kevin Sept. 8, 2019

Sept. 8, 2019

New submission from Kevin <Kfbritton(a)gmail.com>: >>> # Measure some strings: ... words = ['cat', 'window', 'defenestrate'] >>> for w in words: ... print(w, len(w)) ... cat 3 window 6 defenestrate 12 If you need to modify the sequence you are iterating over while inside the loop (for example to duplicate selected items), it is recommended that you first make a copy. Iterating over a sequence does not implicitly make a copy. The slice notation makes this … [View More]

[issue20806] os.times document points to wrong section of non-Linux manual
by Geoffrey Spear Sept. 7, 2019

Sept. 7, 2019

New submission from Geoffrey Spear: The documentation for os.times directs the reader: "See the Unix manual page times(2) or the corresponding Windows Platform API documentation." However, the POSIX manual page in question is times(3P), and on OS X and BSD systems it's times(3). Falling back to "man times" without specifying a manual section also doesn't work, since this finds the bash builtin rather than the library function. ---------- assignee: docs@python components: Documentation … [View More]
