How to use the result of a function to another function in python?

please help I was trying to create Class and Object about pay roll but I got stuck when I tried to use another function to complete the computation for my another funtion

I cant think of any idea how can i use the result of hourly rate to compute my overtime pay, to compute my overtime pay it needs the result of hourly rate and multiply them in my overtime hours

employee1 = Employee("001", "Joss Rees", 700, 24, 4, 500, 1)

class Employee:

    def __init__(self, employee_number, name, daily_rate, days_worked, overtime_hours, cash_advance, days_absent):
        self.employee_number = employee_number
        self.name = name
        self.daily_rate = daily_rate
        self.days_worked = days_worked
        self.overtime_hours = overtime_hours
        self.cash_advance = cash_advance
        self.days_absent = days_absent

    def hourly_rate(self):

        return print(self.daily_rate / 8)

    def monthly_rate(self):
        return print(self.daily_rate * self.days_worked)

    #heres the problem 
    def overtime_pay(self):
        return self.hourly_rate(self) * self.overtime_hours
