for loop - python - changing existing elements in matrix (without array)

Question

I am given a matrix of ints and I need to create a function that does the following - if a number in a cell = 0, the whole column and row needs to change to 0. but I need to change the original matrix, not allowed to make a copy.

I can use only very basic stuff like list of lists, for, if, split I don't know array or complicated numbers.

I hope you can help me please :)
