I want to know how to declare a two dimensional list in Python

Question

I need a data structure in python that can handle data like this in C:

typedef struct lp {
    char pvid[16];
    int ppnum;
} lp_t;

lp_t lpList[100000][3];

Basically, I read in a line, process it, and stuff it to an array lpList[lp#][copy#] for the particular physical partition on a disk. Can you help?

You can define your array as below:

array = []

width = 2
height = 2
array = []
for i in range(height):
    row=[]
    for j in range(width):
        row.append(0)
    array.append(row)

In the example above, you will have an array of 2 by 2 initialise with zeros. If you want to change a value, you can just do:

array[1][1] = 10
