* bpo-38881: choices() raises ValueError when all weights are zero (GH-17362)Raymond Hettinger2019-11-231-1/+3

* bpo-36559: random module: optimize sha512 import (GH-12742)Christian Heimes2019-04-101-1/+8
| | | | | | The random module now prefers the lean internal _sha512 module over hashlib for seed(version=2) to optimize import time. Signed-off-by: Christian Heimes <christian@python.org>

* bpo-35513, unittest: TextTestRunner uses time.perf_counter() (GH-11180)Victor Stinner2018-12-171-2/+2
| | | | | | | TextTestRunner of unittest.runner now uses time.perf_counter() rather than time.time() to measure the execution time of a test: time.time() can go backwards, whereas time.perf_counter() is monotonic. Similar change made in libregrtest, pprint and random.
* Remove unnecessary and over-restrictive type check (GH-10905)Raymond Hettinger2018-12-041-2/+0
|
* Add comments regarding speed/space/entropy trade-offs (GH-10885)Raymond Hettinger2018-12-041-0/+13
|
* Hoist the float conversion out of the inner loop. (GH-10430)Raymond Hettinger2018-11-091-1/+2
| | | Currently, the *n* and *total* variables get converted to floats each time they are multiplied by random(). This minor tweak does the conversion just once and gets a small speedup (approx 3%).
* Minor code refactoring. Compute len() one fewer times on one code path. ↵Raymond Hettinger2018-07-041-4/+4

* bpo-33144: Fix choosing random.Random._randbelow implementation. (GH-6563)Serhiy Storchaka2018-05-081-12/+10
| | | | random() takes precedence over getrandbits() if defined later in the class tree.

* bpo-16500: Don't use string constants for os.register_at_fork() behavior (#1834)Gregory P. Smith2017-05-291-1/+1
| | | | Instead use keyword only arguments to os.register_at_fork for each of the scenarios. Updates the documentation for clarity.
* bpo-16500: Allow registering at-fork handlers (#1715)Antoine Pitrou2017-05-271-0/+5
