Python: string to a list of lists

Viewed 12029

I'm new to python and confused about converting a string to a list. I'm unsure how to create a list within a list to accomplish the following:

Ex.

string = '2,4,6,8|10,12,14,16|18,20,22,24' 

I'm trying to use split() to create a data structure, my_data, so that when I input

print my_data[1][2] #it should return 14

Stuck: This is what I did at first:

new_list = string.split('|')  #['2,4,6,8', '10,12,14,16,', '18,20,22,24']

And I know that you can't split a list so I split() the string first but I don't know how to convert the strings within the new list into a list in order to me to get the right output.
