Python: variables inside class methods

Question

I\'m learning python and am trying to write a wound system based on hot zones of a character. Here\'s what I\'ve written. Don\'t judge me too much.

class Charact         


        

Answer 1

I change my previous answer to this.

class Character:
def __init__ (self, agility, strength, coordination):
        self.max_agility = 100
        self.max_strength = 100
        self.max_coordination = 100
        self.agility = agility
        self.strength = strength
        self.coordination = coordination
        self.l_arm=[]
        self.r_arm=[]
        self.l_leg=[]
        self.r_leg=[]
        self.hit_region_list = [self.l_arm , self.r_arm, self.l_leg, self.r_leg]
        self.healthy = "Healthy"
        self.skin_cut = "Skin Cut"
        self.muscle_cut = "Muscle Cut"
        self.bone_cut = "Exposed Bone"

def hit (self, hit_region, wound):
        self.hit_region = hit_region
        self.wound = wound
        hit_region.append(wound)
        #Hit Zones



        #Wound Pretty Names




john = Character(34, 33, 33)

john.hit(john.l_arm,john.skin_cut)

print john.hit_region
print john.l_arm

After running the above code I got this output

output:
['Skin Cut']
['Skin Cut']

As per the post, I think this is what you wanted. According to your previous code, your declarations were accessible inside a function only. Now You can manipulate the data and these variables for particular instances by declaring them inside the constructor.

Answer 2

Every local variable assigned within a function is thrown away as soon as the function ends. You need to prepend self. to those names so that they are saved as instance variables, such as self.l_arm, self.r_arm, and so on. The same goes for the wound pretty names, if you plan on using those objects later on.

Answer 3

You define l_arm in function and its local to that function only. It has scope of function only. That can be accessed inside function only.

You try to access l_arm outside function, and that gives error, l_arm is not defined.

If you want to access all these variable outside function, you can define it above class

#Hit Zones
l_arm=[]
r_arm=[]
l_leg=[]
r_leg=[]
hit_region_list = [l_arm , r_arm, l_leg, r_leg]


#Wound Pretty Names
healthy = "Healthy"
skin_cut = "Skin Cut"
muscle_cut = "Muscle Cut"
bone_cut = "Exposed Bone"

class Character:
    ...
    ...
    ...

john = Character(34, 33, 33)

john.hit(l_arm, skin_cut)

This will work.
