Hi all,
I found a bug in Python 2.7 involving dictionary comprehensions. I repeatedly
tried to register on the Issue Tracker (http://bugs.python.org/) but never
received a confirmation email, so I still can't log in and post it there. Maybe
someone on this list can post it on my behalf:
>>> functions = {x : lambda y: x + y for x in xrange(10)}
>>> functions[0](0)
9
>>>
The expression "functions[0](0)" should return 0, not 9. It looks like the
scope for variable x is shared across the entire dictionary comprehension
rather than having separate scope for each generated item.
