Lists are very similar to arrays. They can contain any type of variable, and they can contain as many variables as you wish. Lists can also be iterated over in a very simple manner. Here is an example of how to build a list.
mylist =  mylist.append(1) mylist.append(2) mylist.append(3) print(mylist) # prints 1 print(mylist) # prints 2 print(mylist) # prints 3 # prints out 1,2,3 for x in mylist: print(x)
