The standard library has a good selection of functions for working with containers and sequences, for numeric, boolean, and other uses.
- [Instructor] The Python standard library provides…some useful functions for working with containers.…So here in Komodo, I've opened a working copy of…hello.py from chapter 13 of the exercise files,…and I'm just going to start by declaring a tuple,…and I'm going to assign y equals x, and print both of them.…When I run this,…you see we get two copies of the same tuple.…
Now, I can say y equal len of x, l-e-n.…That will give me the length of x,…and you see the y is now the number five.…I can say, y equals reversed…of x, so this will provide me with an iterator,…so when I print it,…we get this reversed object string.…On the other hand, I can create a list out of that,…and that will give me a reversed list…of the tuple in x,…or I could use reversed directly if I wanted to…in a four.…
I could say four, i in y,…print i.…print i.…And you could see we got five, four, three, two, one,…a reversed list.…a reversed list.…There is a sum function.…When I run that, you notice I get the number 15,…which is the sum of one, two, three, four, and five.…
