如何在Python中将数组拆分为列和行？

Question

I have a 2-dim matrix as an input for my function (that input is another function that returns an array with rows and columns). I would like to split that input (array) into width and height so I can use a for loop to access each element. My for loop works fine, however I would like it to work for any array . Now, it runs for a randomised array for which function I specified earlier. Maybe a split function would be useful?

The beginning of my code is

def array_new(column, row):
    new_state = array_rand(column, row) #previous created function

    for r in range(0,row):
        for c in range(0,column):
        ....

I would like to have something like

def array_new(array):

and then split the array into rows and columns.

Hope my question is understandable.

A python list is already "split" into rows. You can iterate over them with a for loop:

def array_new(array):
    for row in array:
        # do something with the row
