Iterating over key/value pairs in a dict sorted by keys

Question

I have the following code, which just print the key/value pairs in a dict (the pairs are sorted by keys):

for word, count in sorted(count_words(filename).items()         


        

Answer 1

As per Marks answer: In Python 2, use iteritems(), in Python 3 use items().

And additionally; If you need to support both (and don't use 2to3) use:

counts = count_words(filename)
for word in sorted(counts):
     count = counts[word]
