>Solution :

You have asked why the variables in the method sfunc() (or "def number 3") are not defined.

The things that are not defined (technically attributes from the class rather than "variables") are named age and salary. It looks like you attempted to initialize these in the constructor _init_() but used different names (Employeeage and Employeesalary).

Try this instead:

class Employee:
    def __init__(self,name,age,salary,rating):
        self.name=name
        self.age =age
        self.salary =salary
        self.rating=rating
    def myfunc (self):
        if self.rating <= 2.5:
            print('BAD')
        else:
            print('GOOD')        
    def sfunc (self):
        if self.age <= 60: #here age is not defined
             self.salary+=5000 #here salary is not defined
             print(f'salary is {self.salary}')

e = Employee('Brad Pitt',58,1000000,9.9)
e.myfunc()
e.sfunc()

Output:

GOOD
salary is 1005000
