* Teach the random module about os.urandom().Raymond Hettinger2004-08-301-2/+16
| | | | | * Use it for seeding when it is available. * Provide an alternate generator based on it.
* SF bug #812202: randint is always evenRaymond Hettinger2003-10-051-0/+12
| | | | | | | * Added C coded getrandbits(k) method that runs in linear time. * Call the new method from randrange() for ranges >= 2**53. * Adds a warning for generators not defining getrandbits() whenever they have a call to randrange() with too large of a population.
* Removed deprecated functionsRaymond Hettinger2003-08-051-12/+0

* Improve comments. Clarify docs.Raymond Hettinger2002-11-181-11/+12
| | | | | Replace "type(0)" with "int". Replace "while 1" with "while True"
* SF patch 629637: Add sample(population, k) method to the random module.Raymond Hettinger2002-11-121-0/+19
| | | | Used for random sampling without replacement.
* Markup adjustments; fix the names of modules referenced in an expression.Fred Drake2002-05-231-2/+2
|
* Deprecated Random.cunifvariate clearing bug 506647. Also, added docstrings.Raymond Hettinger2002-05-231-1/+4

* Closes SF bug 527139. Brings docs inline with random.py 1.29Raymond Hettinger2002-05-131-1/+1

* Correct gammavariate's method name and domain.Raymond Hettinger2002-05-131-2/+2

* Change random.seed() so that it can get at the full range of possibleTim Peters2001-02-011-14/+29
| | | | | | | | internal states. Put the old .seed() (which could only get at about the square root of the # of possibilities) under the new name .whseed(), for bit-level compatibility with older versions. This occurred to me while reviewing effbot's book (he found himself stumbling over .seed() more than once there ...).

* Fix bugs introduced by rewrite (in particular, time-based initializationTim Peters2001-01-251-8/+19
| | | | | | | got broken). Also added new method .jumpahead(N). This finally gives us a semi-decent answer to how Python's RNGs can be used safely and efficiently in multithreaded programs (although it requires the user to use the new machinery!).
* Reworked random.py so that it no longer depends on, and offers all theTim Peters2001-01-251-31/+55
| | | | | | | | | | | functionality of, whrandom.py. Also closes all the "XXX" todos in random.py. New frequently-requested functions/methods getstate() and setstate(). All exported functions are now bound methods of a hidden instance. Killed all unintended exports. Updated the docs. FRED: The more I fiddle the docs, the less I understand the exact intended use of the \var, \code, \method tags. Please review critically. GUIDO: See email. I updated NEWS as if whrandom were deprecated; I think it should be.

* Clean up the docs for the "random" module according to comments from TimFred Drake2001-01-221-90/+71

* Remove all uses of \sectcode; we can now use logical markup everywhere.Fred Drake1998-04-041-1/+1
|
* Remove obsolete lines like this:Fred Drake1998-04-041-1/+0
| | | | | | | | \setindexsubitem{(in module frobnitz)} These are no longer needed when present before any other \setindexsubitem{} in the module section. The indexsubitem is now set by \bimodindex and \stmodindex.
* Consistency nits:Fred Drake1998-04-031-3/+3
| | | | | | Use math-mode pi instead of mixing forms. Use spaces around relational operators.
* Markup adjustments.Fred Drake1998-03-081-23/+25
|
* Remove all \bcode / \ecode cruft; this is no longer needed. See previousFred Drake1998-02-131-1/+1
| | | | | | | | | checkin of myformat.sty. Change "\renewcommand{\indexsubitem}{(...)}" to "\setindexsubitem{(...)}" everywhere. Some other minor nits that I happened to come across.
