New submission from Tomáš Dvořák <dvto...@gmail.com>:
I have this python script, and run it in python 2.7.2 (installed from EPD_free
7.1-2 (32-bit), but I guess this has nothing to do with EPD.
----8<---fail.py------
class X(object):
pass
x = X()
items = ["foo", "bar", "baz"]
for each in items:
setattr(x, each, lambda: each)
print("foo", x.foo())
print("bar", x.bar())
print("baz", x.baz())
----8<---fail.py------
I'd naively expect it to print
('foo', 'foo')
('bar', 'bar')
('baz', 'baz')
,but it surprisingly (and annoyingly) outputs
('foo', 'baz')
('bar', 'baz')
('baz', 'baz')
Please, tell me that this is a bug :) I'd hate it if this was the intended
behaviour. I spent two hours today before I found out this was the cause of my
program to fail.
Best regards,
Tomáš Dvořák
