Answer to Coding Problem 3.4.9 that references 2.4.4 on Pokemon:

def calculate_modifier(STAB, Type, Critical, Other, Random):

mod = STAB * Type * Critical * Other * Random * 1

return mod

def calculate_damage(STAB, Type, Critical, Other, Random, Level, Attack, Defense, Base):

A = (2 * Level + 10)/250

B = Attack/Defense

C = Base

Total_Damage = ((A * B * C + 2) * calculate_modifier(STAB, Type, Critical, Other, Random))

return Total_Damage
