Using the Counter function on a list in python -

-

we have return frequency of length of words in .txt file. e.g "my name emily" converted list: ["my", "name", "is", "emily"], converted list of lengths of each word: [2, 4, 2, 5] , use function counter outputs dictionary looks like:

counter({2: 2, 4: 1, 5: 1})

but need include count of zero: 

counter({1: 0, 2: 2, 3: 0, 4: 1, 5: 1})

any ideas? should rid of counter function together?

counter counts frequency of items, means keeps count of items present.

but, if item looking not there in counter object, return 0 default.

for example,

print counter()[1] # 0

if need items 0 count in it, can create normal dictionary out of counter, this

c = counter({2: 2, 4: 1, 5: 1}) print {num:c[num] num in xrange(1, max(c) + 1)} # {1: 0, 2: 2, 3: 0, 4: 1, 5: 1}
