Jon Dufresne 3972628de3 bpo-30296 Remove unnecessary tuples, lists, sets, and dicts (#1489) 
* Replaced list(<generator expression>) with list comprehension
* Replaced dict(<generator expression>) with dict comprehension
* Replaced set(<list literal>) with set literal
* Replaced builtin func(<list comprehension>) with func(<generator
  expression>) when supported (e.g. any(), all(), tuple(), min(), &
  max())

This hides unwanted implementation details from tracebacks.

Antoine Pitrou de89d4b097 Port 2.7 fix for sporadic failure in test_weakset. 2012-03-04 20:20:34 +01:00
Antoine Pitrou bbe2f60b3c Issue #14159: Fix the len() of weak containers (WeakSet, WeakKeyDictionary, WeakValueDictionary) to return a better approximation when some objects are dead or dying. 
Moreover, the implementation is now O(1) rather than O(n).
Thanks to Yury Selivanov for reporting.

Georg Brandl bf93b0470a Fix two issues in the weak set implementation. 2008-05-18 07:46:13 +00:00
Raymond Hettinger 93fa608626 Moved WeakSet into a bootstap module use by abc.py. 
This makes it possible to use ABCs in weakref.py
(which will be done in a later checkin).
