New submission from Chris Angelico:
Only noticed because I was searching the stdlib for hasattr calls, but in
mailbox.Mailbox.update(), a check is done thus:
if hasattr(arg, 'iteritems'):
source = arg.items()
elif hasattr(arg, 'items'):
source = arg.items()
else:
source = arg
If this is meant to support Python 2, it should probably use iteritems() in the
first branch, but for Python 3, it's probably simpler to just drop the first
check altogether:
if hasattr(arg, 'items'):
source = arg.items()
else:
source = arg
Or possibly switch to EAFP:
try:
source = arg.items()
except AttributeError:
source = arg
