Question

I want to output the reult of this program onto a txt file, and I also need to add 1 list; 1 dictionary(dictionary value should be a complex object, not just a simple value such as number or string), exceptions (try … except)

class Animal:
animal_type = None
name = None
available_for_adoption = None
def __init__(self, animal_type, name, available_for_adoption):
self.animal_type = animal_type
self.name = name
self.available_for_adoption = available_for_adoption

class PetStore:
animals = None
def __init__(self):
self.animals = []

def add_animal(self, animal):
self.animals.append(animal)

def delete_animal(self, name):
for animal in self.animals:
if animal.name == name:
self.animals.remove(animal)
return True
return False

petstore = PetStore()
choice = input("Pet Store Options ----------- 1. Add Animal 2. Delete Animal 3. Show Animals 4. Exit What would you like to do? ")

while choice!=4:
if choice == 1:
animal_type = raw_input("What type of animal would you like to create? ")
name = raw_input("What is the animal's name? ")
a = raw_input("Is the animal available for adoption?(y/n) ")
if a=='y':
available_for_adoption = True
else:
available_for_adoption = False
animal = Animal(animal_type, name, available_for_adoption)
petstore.add_animal(animal)

elif choice == 2:
name = raw_input("What is the animal's name you'd like to remove? ")
deleted = petstore.delete_animal(name)
if deleted:
print name+" has been removed."
else:
print name+" could not be found"

elif choice == 3:
print "Animal List ----------- "
for animal in petstore.animals: #nested loops
if animal.available_for_adoption==True:
avail = "is available"
else:
avail = "is not available"
print animal.name + " is " + animal.animal_type + " and " +avail

choice = input("Pet Store Options ----------- 1. Add Animal 2. Delete Animal 3. Show Animals 4. Exit What would you like to do? ")

print "Thank you for visiting the Pet Store!"
