Question

I have this bit of code:

    visits = defaultdict(int)     for t in tweetsSQL:          visits[t.user.from_user] += 1 

I looked at some examples online that used the sorted method like so:

sorted(visits.iteritems, key=operator.itemgetter(1), reverse=True)

but it is giving me:

'TypeError: 'builtin_function_or_method' object is not iterable'

I am not sure why.

Answer 1

iteritems is a method. You need parenthesis to call it: visits.iteritems().

As it stands now, you are passing the iteritems method itself to sorted which is why it is complaining that it can’t iterate over a function or method.
