Hello, I have the following code:

import csv

def carregar_acessos():

    X = []
    Y = []

    arquivo = open('acesso_pagina.csv', 'rb')
    leitor = csv.reader(arquivo)
    next(leitor)


    for home,como_funciona,contato,comprou in leitor:

        dado = [int(home),int(como_funciona),int(contato)]
        X.append(dado)
        Y.append([int(comprou)])

It attempts to retrieve information from a CSV file containing several ZEROS and UNS. And I have another file that shows this in the terminal:

from dados import carregar_acessos

X,Y = carregar_acessos()

print(X)
print(Y)

But when I run the code the following error appears:

Traceback (most recent call last):
  File "classifica_acesso.py", line 3, in <module>
    X,Y = carregar_acessos()
  File "/Users/josecarlosferreira/Desktop/machine-learning/dados.py", line 10, in carregar_acessos
    next(leitor)
_csv.Error: iterator should return strings, not bytes (did you open the file in text mode?)

Well, I saw some answers in Stackoverflow in English, but even trying the solutions proposed there, the code did not work and still kept the same error.

CSV is created this way:

home,como_funciona,contato,comprou
1,1,0,0
1,1,0,0
1,1,0,0
1,1,0,0
1,1,0,0
1,0,1,1
1,1,0,0
1,0,1,1
1,1,0,0
1,0,1,1

And it goes on for 200 more lines. They each indicate a SIM (1) and NO (0) information. Could someone help me?
