Lists are an essential Data Structure that every one may use one day,
They allow us to group together multiple values and reference them all with the same name.
numbers = [1,2,3]
a list can hold values of different Types:
items = ["hi",2,3,4,"text"]
we can check if an item is contained into a list with the
we can reference the items in a list by their index , starting from zero :
items # "hi" items # 2
using the same notation we can change the value stored at a specific index:
items = "bye"
we can also use the the
index() method, this will return to us what is stored at these index .

we can get the number of items contained in a list using the
len() global function, the same we used to get the length of the string
adding the Items can be done with
append() method, or the extend method like this
