[issue28235] In xml.etree.ElementTree docs there is no parser argument in fromstring()

Berker Peksag added the comment: Instead of duplicating XML() documentation, I'd suggest changing fromstring() documentation to say something like "this is an alias for ElementTree.XML()." -- nosy: +berker.peksag versions: +Python 3.5, Python 3.7 ___

[issue28242] os.environ.get documentation missing

Ned Deily added the comment: The difference is that os.environ is a reference to a mapping object, essentially a dict, that has all of the process environment variables. By using the get('x') method on that object, you ask the object to find and return the value corresponding to key 'x' or to

[issue28243] Performance regression in functools.partial()

New submission from Serhiy Storchaka: There is 10% performance regression in calling functools.partial() in 3.6. $ ./python -m perf timeit -s 'from functools import partial; f = lambda x, y: None; g = partial(f, 1)' -- 'g(2)' Python 3.5: Median +- std dev: 452 ns +- 25 ns Python 3.6: Median

[issue28240] Enhance the timeit module: display average +- std dev instead of minimum

Marc-Andre Lemburg added the comment: We had a similar discussion a while back for pybench. Consensus then was to use the minimum as basis for benchmarking: https://mail.python.org/pipermail/python-dev/2006-June/065525.html I had used the average before this discussion in pybench 1.0: https://

[issue28243] Performance regression in functools.partial()

STINNER Victor added the comment: Oh, functools.partial.__call__() doesn't use fastcall yet. So compared to Python 3.5, fastcall shouldn't explain a major performance difference. FYI I'm working on an extension of fastcall to also support fastcall calling convention for obj.__call__() ;-) But

[issue27400] Datetime NoneType after calling Py_Finalize and Py_Initialize

Jim Jewett added the comment: Having to (re-)fill the cache once per interpreter seems like a reasonable price to pay. Why is 3.5 not included? Did this not cause problems before the import change, or is it just that this bug is small enough that maybe it isn't worth backporting? --

[issue26351] Occasionally check for Ctrl-C in long-running operations like sum

Terry J. Reedy added the comment: The request is to check 'occasionally'. To me this means perhaps once a second, which is to say, ^c should generally interrupt within a second, and on average with half a second. The following takes just under a second: "sum(i for i in range(1000))" wher
