"""
DefaultDict is a container in the collections class of Python. It is almost the same as the usual dictionary (dict) container but with one difference. The value fields' data-type is specified upon initialization. 
A basic snippet showing the usage follows:

from collections import defaultdict
d = defaultdict(list)
d['python'].append("awesome")
d['something-else'].append("not relevant")
d['python'].append("language")
for i in d.items():
    print i
This prints:

('python', ['awesome', 'language'])
('something-else', ['not relevant'])
