Object not callable in Python Abstraction

Question

Hi can someone tell me why the below code shows the error, I think this should run fine -

from abc import ABC, abstractmethod
class DriveStrategy(ABC):
    @abstractmethod
    def drive_strategy(self):
        pass
    
class NormalDrive(DriveStrategy):
    def drive_strategy(self):
        print("Normal Drive")

class SpecialDrive(DriveStrategy):
    def drive_strategy(self):
        print("Special Drive")
        
        
class Vehicle:
    def __init__(self, drive: DriveStrategy):
        self.drive = drive
    
    def drive(self):
        self.drive.drive_strategy()

class SUV(Vehicle):
    def just_a_method(self):
        print("from SUV")

class PassengerBus(Vehicle):
    def bus_method(self):
        print("From Bus")

safari = SUV(SpecialDrive())
safari.drive()

It shows 'SpecialDrive' object is not callable

Expecting that to print "Special Drive".

Answer 1

The problem of this code is in Class Vehicle, the variable name self.drvie is same with the function drive(). To solve this problem, you just need to use another name for the function. There is an example:

class Vehicle:
    def __init__(self, drive: DriveStrategy):
        self.drive = drive

    def Drive(self):
        self.drive.drive_strategy()
