Question

I have the following code:

for i in range(w[n], W):
    array[n][i] = v[n]

In python this give an out of index error because I am not using append…how would I right the above in order to work in python???

All help will be appreciated! Thank You!

First of all, you shouldn’t use the name ‘array’ for an array. Even though it’s not a reserved name in python, it’s considered bad programming practice. A way to do what you want is like this:

myArr = [[0 for col in range(n)] for row in range(W)]
for i in range(w[n], W):
            myArr[n][i] = v[n]

The first line creates an array of [n][W] elements initialized to 0. It’s the easiest way to achieve this in python without adding an extra dependency.
