Perhaps you meant

for i in range(kk):

a bit off topic, but:

for i in temp.keys():
    key = i
    num = [int(frequency[key])]
    tvalues += num

should just be:

tvalues = temp.values()

example:

>>> D = {'a':1, 'b':2, 'c':3, 'd':4}
>>> D.keys()
['a', 'c', 'b', 'd']
>>> D.values()
[1, 3, 2, 4]
>>> D.items()
[('a', 1), ('c', 3), ('b', 2), ('d', 4)]
>>> 

and it looks like your code could be changed to this:

>>> D = {'a':1, 'b':2, 'c':3, 'd':4}
>>> def get_top_k(D, k):
...     return sorted(D.items(), reverse=True, key=lambda x: x[1])[:k]
... 
>>> get_top_k(D, 2)
[('d', 4), ('c', 3)]
>>>

You have for i in kk and kk is just an integer. You can't iterate over an integer, you can only iterate over a sequence/iterable.

You probably want for i in range(kk) if you want to iterate from 0 to (kk-1).

Because kk = int(k)

kk is only one single number, not an array of numbers

What are you trying to do, for us to help you fixing it?
