Let's dig deeper into managing lists and how to update the data inside them, like how temperature data might change throughout the day.
Lists can store any piece of data, be it string, boolean, float or integer like 17.
Every element in a list has a numbered position called an index.
Indices start at zero and increase with each further value. That means that the second element in temperatures is at index [1].
>>> temperatures = [17,20,26,24]
>>> temperatures[1]
20
>>> temperatures[-1]
24
