Ordered lists in Python are lists or tuples where lists are mutable and tuples are not. Lists and tuples may be accessed by index or by slices.
- The basic sequential types in Python are lists and tuples.…Lists are mutable and tuples are not.…Here in Komodo, I've opened a working copy of list.py…from chapter eight of the exercise files.…And here we define a list,…to notice that the square brackets…are used to create the list.…A list is an ordered collection, it's sequential…and it's interval.…And you'll notice down here in our print list function,…we're iterating with the foreloop.…
So when I run this, it lists in order,…each of the elements in the list,…rock, paper, scissors, lizard, Spock.…I can access an individual item in the list…using an index.…So I can say print game sub one, like this.…And if I run that, you'll see we get paper.…Lists are zero-based so item number zero would be rock,…item number one would be paper.…
So the first number is the beginning of the slice…and the second number is the end of the slice noninclusive.…So in other words, this would be items number one and two.…So this would be paper and scissors.…And if I run this, see we get paper and scissors.…
