Sorted Word frequency count using python

Question

I have to count the word frequency in a text using python. I thought of keeping words in a dictionary and having a count for each of these words.

Now if I have to so

Answer 1

You can use the same dictionary:

>>> d = { "foo": 4, "bar": 2, "quux": 3 }
>>> sorted(d.items(), key=lambda item: item[1])

The second line prints:

[('bar', 2), ('quux', 3), ('foo', 4)]

If you only want a sorted word list, do:

>>> [pair[0] for pair in sorted(d.items(), key=lambda item: item[1])]

That line prints:

['bar', 'quux', 'foo']
