Is it possible to use results from other function into a new list?

I want to make a new list including the results from all three def functions and I do not know how. I am expecting to add all three results from the sites into a new list and then find the lowest price from the list, the highest price, maybe average price(but these i think I can do them by myself).
I am new to coding. Please don’t down vote 🙂

>Solution :

You can concatenate the 3 lists into 1 list as following:

import itertools
all_cars = list(itertools.chain(result1, result2, result3))

now you will be able to find minimal and maximal values as following:

minimal_price = min(all_cars)
maximal_price = max(all_cars)

As about average value – there are several ways to get it, I’d prefer this:

average_price = sum(all_cars) / len(all_cars)
