Some times, I want to count elements in list object.
Elements are words, smiles;-), and any more.
When I did it, I made dictionary that has keys in each elements and count it.
Like follow..
listobj = list("aabcabbccc")
dict = {}
for i in listobj:
if dict.has_key(i):
dict[i] += 1
else:
dict[i] = 1
But Today, I knew more efficient method, “collections”.
I feel more better.
form collections import Counter
listobj = list("aabcabbccc")
collection = Counter( listobj )
for key, val in collection.most_common():
print key, val
Then I could get
c 4 a 3 b 3
That’s nice !
