So a quick overview of we've learned so far,
0:02
namedtuples, an elegant and readable way to create tuples,
0:07
and instead of user index zero, and index one,
0:10
you can say user.name and user.role.
0:13
A defaultdict is great way
0:15
to buildup a nested data structure,
0:18
you don't get key errors, because the internals
0:20
make sure that the value gets initialized
0:23
before appending to it.
0:25
Counter, don't reinvent the wheel,
0:28
so here at the top you see all the code
0:30
I needed to get the top five words in a string,
0:34
and below we did the same,
0:35
but only with one line of code, very powerful.
0:38
A deque, so lists are your best friend,
0:41
but if you have to insert at them at the start,
0:45
for example, they get very slow.
0:48
So deques are great if you need to insert
0:50
and remove at both ends of the sequence.
0:52
And now it's your turn.
