Greetings

Here is a module for card game that i have been working on, it returns an __str__ error of None type, need some help:



# Modulo Cartas

class Carta(object):
""" Um baralho """

NUMERO = ["A", "2", "3", "4", "5", "6", "7",
"8", "9", "10", "J", "Q", "K"]
NAIPE = ["e","p","c","o"]

def __init__(self, numero, naipe):
self.numero = numero
self.naipe = naipe

def __str__(self):
rep = ""
rep += self.numero + self.naipe
return rep


class Baralho(object):
"""Um conjunto de 52 cartas."""

def __init__(self):
self.baralho = []

def populate(self):
for num in Carta.NUMERO:
for naip in Carta.NAIPE:
self.baralho.append(Carta(num,naip))

def __str__(self):
if self.baralho:
rep = ""
for carta in self.baralho:
rep += str(carta)
else:
rep += "vazio"

def baralhar(self):
import random
random.shuffle(self.baralho)

def dar_carta(self, outra_mao, carta, x_dar = 1):
for i in x_dar:
outra_mao.append(carta)

def reunir_cartas(self):
for num in Carta.NUMERO:
for naip in Carta.NAIPE:
self.baralho += [num,naip]
random.shuffle(self.baralho)

class Mao(Baralho):

def __init__(self):
self.mao = []

def __str__(self):

if self.mao:
rep = ""
for carta in self.mao:
rep += str(carta)
else:
rep += "<Sem cartas em mao...>"


# Teste de modulo


carta1 = Carta("A","p")
print carta1


baralho1 = Baralho()
baralho1.populate()
print baralho1

Your problem is that you aren't returning a value from your __str__ functions so it defaults to NoneType.

This code works. Also, when you post code, use code tags, because python can be extremely hard to decipher when the indentation is stripped.


code goes here.

def __init__(self, numero, naipe):
self.numero = numero
self.naipe = naipe

def __str__(self):
rep = ""
rep += self.numero + self.naipe
return rep
