Hello,
The following behaviour seen in 3.2 seems very strange to me:
As expected:
>>> () == []
False
However:
>>> ().__eq__([])
NotImplemented
>>> [].__eq__(())
NotImplemented
And:
>>> bool(NotImplemented)
True
Hence:
>>> bool(().__eq__([]))
True
>>> ( () == [] ) != ( ().__eq__([]) )
True
Ho

You have to iterate.
Either with
for u in users:
fob.write( u + '\n' )
or with a lambda function.
always a good call: http://python.org/
