# Makes list, note in python when addressing an element, the first element is 0, the second is 1. a = [1,2,3,4] # [0,1,2,3] shows how python "reads" the location. # Prints elements in list a print a # deletes the "first" element which is element 0 del a # prints the elements in list a, minus the original 1 value in the 0 place. print a
