Python: How do I refer to an attribute of a class by an attribute of another class or a variable?

Question

I am trying to create a magic system in my text-based RPG that refers to an attribute of a monster class using the attribute from the magic class. The monster class looks like

class monster(object):
    def __init__(self, **kwargs):
        self.__dict__.update(kwargs)

with the list of monsters being store in the format

bestiary = { 
99999: monster(name="Slime", currentHP= 3, maxHP= 10, initiativeMod= 1, AC= 0, baseAttack= 0, equippedWeapon= itemsList[13], speed = 10) ##Syntax items 
}

The spells are created in the form

class BuffSpell(object):
def __init__(self, **kwargs):
    self.__dict__.update(kwargs)

with instances of each spell in the form

bardSpells = {
    2: BuffSpell(name= "Flare", level= 0, stat= "baseAttack", value = -1, MP = 3, spellType = "buff"),
}

I am trying to refer to an attribute in monster that is given by an attribute in the spell like this

def useMagic(target, spell):
if spell.spellType == "buff":
    x = spell.stat
    target.x += spell.value

which of course doesn't work. How can I get the spell.stat attribute and apply spell.value to the corresponding attribute in monster?

You could try something like the following:

def use_magic(target, spell):
    if spell.spell_type == "buff":
        stat = spell.stat
        setattr(target, stat, getattr(target,stat) + spell.value)
