Create an empty list:
my_list = []
Add an element to a list:
my_list.append("some string")
my_list.append(7)
this list will now have two elements my_list[0] will contain "some string" and my_list[1] will contain the integer value of 7
Length of a list: find out the number of elements in a list -- just like finding the length of a string
len(my_list)
Insert an element at a given position in the list:
a_list = ["some words", "in a","simple", "list" ]
a_list.index(1,"and strings")
a_list will now contain: ["some words","and strings", "in a","simple", "list" ]
