    def request_bikes(self,stock,unique_number,family_rent,salary):
        customer = Customers(stock,unique_number,family_rent,salary)
        self.all_accounts[stock,unique_number] = customer 
        for key,value in self.all_accounts.items():
            print(key)

customer = Customers(5 , 40607 , 4 , 5000)
bike = BikeRental()
bike.request_bikes(3,50607 , 5 , 6000)

Answer

If you just wanted to store all information in a dictionary in request_bikes function then you can use something like below

def request_bikes(self, stock, unique_number, family_rent, salary):
    customer = Customers(stock, unique_number, family_rent, salary)
    #self.all_accounts[stock, unique_number] = customer
    self.all_accounts['stock']= customer.stock
    self.all_accounts['unique_number'] = customer.unique_number
    self.all_accounts['family_rent'] = customer.family_rent
    self.all_accounts['salary'] = customer.salary
    return self.all_accounts
