How do I make a function read a row and a column with only zeros without using libraries

I’m new to programming in general… I have to check all the rows and columns of an matrix and in case any of them are complete with zeros, return a True value. I made this code in a silly attempt but it doesn’t work for the purpose of the question itself. The matrix will always be a square and a list of lists.

def determinanteEhNulo(matriz):
  contador = 0
  
  for i in matriz:
    for j in range(len(matriz)):
      if i[j] == 0:
        contador += 1

  if contador >= int(len(matriz)):
    return True
  return False

>Solution :

This seems to do what you need.

def determinanteEhNulo(matriz):
    for i in matriz:
        if all(x==0 for x in i):
            return True
    for i in zip(*matriz):
        if all(x==0 for x in i):
            return True
    return False
