not able to define variable inside of decorated method

Question

#Not exactly sure why the code is always using 1.2 when I redefine raise_percentage
raise_percentage=1.2
class worker:
def __init__(self,age,pay):
self.age=age
self.pay=pay

def Raise(func):
def wrapper(self):
#as you can see I define raise_percentage by the amount I want to increase
#wage by but it always refers back to the initial value 1.2.
if self.age<30:
raise_percentage=1.2
func(self)
print("under 30")
elif self.age<40:
raise_percentage=1.1
func(self)
print("under 40")
elif self.age<50:
raise_percentage=1.05
func(self)
print("under 50")
else:
raise_percentage=1
func(self)
print("over 50")

return wrapper

def func(self):
print( self.pay*raise_percentage)

Raised=Raise(func)

Bob=worker(24,20000)
Carl=worker(36,34000)
Jessica=worker(43,41000)

Jessica.Raised()

Answer 1

Never use 'global' with object oriented programming : it is a bad programming practice.

Convert 'raise_percentage' to a class variable instead, it would be way better.

Answer 2

Théophile Oh yeah you're right it is. I forgot it is a class. Thanks!

Answer 3

Add

global raise_percentage

inside Raise function in order to affect the variable "raise_percentage" because "raise_percentage" is a global variable and global variables are not affected by functions unless you include "global" inside the function like above.

I hope this helps. Happy Coding!

Answer 4

Thanks so much guys. I'm still pretty new to coding so was confused by this one

Answer 5

Sean Place the variable inside the class (often at above) outside funcions or methods.
Like this

Class worker:
raise_percentage = 1.2

def __init__ (self, age, pay)
....

Answer 6
