0:01 Welcome back to the 100 days of Python.
0:03 In the coming three days I will guide you
0:04 through the collections module,
0:06 a very convenient module
0:08 to work with more advanced data structures.
0:10 First we look at namedtuples
0:12 and how they can make your code
0:13 more readable and elegant.
0:15 Next we look at defaultdict,
0:17 which is convenient to build up
0:18 a nested data structure.
0:20 Third, counter, saves a lot of code
0:22 to find the most common thing in a collection,
0:26 and lastly, deque, which can tremendously improve
0:29 your performance based on the operations
0:31 you want to do on your sequence,
0:33 and for the second and third day
0:35 I got a movie dataset
0:36 where you can put the collections module into practice.
