a = ["poko", "poko", "hoge", "aaa", "aaa", "poko", "aaa", "aab"]
There is a list like
from collections import Counter
counts = Counter(a)
#Top 2
print counts.most_common(2)
# [Out]: [('poko', 3), ('aaa', 3)]
#All from the top
print counts.most_common()
# [Out]: [('poko', 3), ('aaa', 3), ('aab', 1), ('hoge', 1)]
#key specification
print counts[“poko”]
# [Out]: 3
Can be used like a sorted dict (is it okay to say something like this?)
