I am trying to use a __str__ method to display the values of attribute
mood = self.hunger + self. boredom.
When I try to execute I get this error:
Traceback (most recent call last):

print(crit)
TypeError: __str__ returned non-string (type int)
Then return a str instead of int.
This is the code:
# Critter Caretaker
# A virtual pet to care for
import random
class Critter(object):
"""A virtual pet"""
def __init__(self, name, hunger = 0, boredom = 0):
self.name = name
self.hunger = hunger
self.boredom = boredom
def __pass_time(self):
self.hunger += 1
self.boredom += 1
def __str__(self):
mood = self.boredom + self.hunger
return mood
Change to:
return str(mood)
Cheers,
Timo
