#Below is how you create a class - there are lots of things going on, but we
#will explore these in more detail in the relevant section of the book. For now
#suffice to say that this class contains attributes and methods (i.e. functions
#that a zookeeper might find useful.

class Animal:
    animal_list = []
    animal_count = 0
    def __init__(self, name, gender, species, age):
        self.name = name
        self.gender = gender
        self.species = species
        self.age = age
        Animal.animal_list.append(self)
        Animal.animal_count = Animal.animal_count + 1
    def displayCount():
        print("There are " + str(Animal.animal_count) + " animals in the zoo.")
    def displayAnimal(self):
        print(self.name + " is a " + self.gender + " " + self.species + ".")
        print(self.name + " is " + str(self.age) + " years old.")

#So the "blueprint" bit of the class is outlined above, but we need to fill it
#with entries - below is a list of animals in the zoo, and various properties
#of them. This is how you assign things to the class we've just built.

gill = Animal("Gill", "female", "bison", 14)
bruce = Animal("Bruce", "male", "zebra", 7)
tony = Animal("Tony", "male", "orangutan", 22)
rebecca = Animal("Rebecca", "female", "tree frog", 1)
sweaty = Animal("Sweaty", "male", "fox", 34)
slippy = Animal("Slippy", "female", "penguin", 4)

#Now try playing around with each animal's attributes - let's call up certain
#bits of information about the animals in the zoo. Type this into the shell:
tony.species
sweaty.age
slippy.gender

#Now try playing around with the class methods (i.e. functions) we built in.
#Start by typing the following function calls into the shell:
"""
Animal.displayCount()
Animal.displayAnimal(rebecca)
