|
* bpo-41421: Algebraic simplification for random.paretovariate() (GH-21695)Raymond Hettinger2020-08-011-1/+1
|

|
* bpo-40541: Add optional *counts* parameter to random.sample() (GH-19970)Raymond Hettinger2020-05-081-5/+29
|
* bpo-40465: Deprecate the optional argument to random.shuffle(). (#19867)Raymond Hettinger2020-05-021-0/+4
|
* Simplify choice()'s interaction with the private _randbelow() method (GH-19831)Raymond Hettinger2020-05-011-9/+5
|
* bpo-40286: Remove C implementation of Random.randbytes() (GH-19797)Victor Stinner2020-04-291-0/+6
| | | | | Remove _random.Random.randbytes(): the C implementation of randbytes(). Implement the method in Python to ease subclassing: randbytes() now directly reuses getrandbits().
* bpo-40325: Deprecate set object support in random.sample() (GH-19591)Raymond Hettinger2020-04-191-1/+4
|
* bpo-40282: Allow random.getrandbits(0) (GH-19539)Antoine Pitrou2020-04-171-2/+4
|
* bpo-40286: Add randbytes() method to random.Random (GH-19527)Victor Stinner2020-04-171-0/+7
| | | | | | | | | | | | Add random.randbytes() function and random.Random.randbytes() method to generate random bytes. Modify secrets.token_bytes() to use SystemRandom.randbytes() rather than calling directly os.urandom(). Rename also genrand_int32() to genrand_uint32(), since it returns an unsigned 32-bit integer, not a signed integer. The _random module is now built with Py_BUILD_CORE_MODULE defined.
* bpo-38881: choices() raises ValueError when all weights are zero (GH-17362)Raymond Hettinger2019-11-231-1/+3
|
* bpo-32554: Deprecate hashing arbitrary types in random.seed() (GH-15382)Raymond Hettinger2019-08-221-2/+13
|
* bpo-37116: Use PEP 570 syntax for positional-only parameters. (GH-13700)Serhiy Storchaka2019-06-011-1/+1
|
* 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>
* Convert range to repeat for choices() (#11889)Raymond Hettinger2019-02-161-3/+3
|
* Be consistent about the use of from-imports in random module (GH-11837)Raymond Hettinger2019-02-131-4/+4
| | | Minor code clean-up.
* bpo-35782: Fix error message in randrange (GH-11620)Kumar Akshay2019-01-211-1/+1
| | | https://bugs.python.org/issue35782
* bpo-30561: Sync-up expovariate() and gammavariate code (GH-1934)leodema2018-12-241-4/+1
|
* 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
| | | | (GH-8094)
* bpo-24567: Random subnormal.diff (#7954)Raymond Hettinger2018-06-271-1/+3
| | | | | Handle subnormal weights for choices()
* 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-33144: random.Random and subclasses: split _randbelow implementation ↵Wolfgang Maier2018-04-171-14/+38
| | | | (GH-6291)
* bpo-33203: Ensure random.choice always raises IndexError on empty sequence ↵Wolfgang Maier2018-04-051-0/+2

* 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
| | | | | | | | | | | | * bpo-16500: Allow registering at-fork handlers * Address Serhiy's comments * Add doc for new C API * Add doc for new Python-facing function * Add NEWS entry + doc nit
