Missing charge_phone() method in Your-Journey-To-Fluent-Python /15.Introduction-to-OOP.md

[Stephanie-H952]

Here is the original code:

class Smartphone:
def init(self, brand, model):
self.brand = brand # Public attribute
self.model = model # Public attribute
self.__battery_level = 100 # Private attribute (initially fully charged)
self._installed_apps = [] # Protected attribute (initial app list)

def install_app(self, app_name):
    """Public method to install a new app."""
    if app_name not in self._installed_apps:
        self._installed_apps.append(app_name)
        print(f"App '{app_name}' installed.")
    else:
        print(f"App '{app_name}' is already installed.")

def uninstall_app(self, app_name):
    """Public method to uninstall an app."""
    if app_name in self._installed_apps:
        self._installed_apps.remove(app_name)
        print(f"App '{app_name}' uninstalled.")
    else:
        print(f"App '{app_name}' is not installed.")

def show_installed_apps(self):
    """Public method to display installed apps."""
    print("Installed Apps:", self._installed_apps)

def __check_battery(self, required_amount):
    """Private method to check if enough battery is available."""
    return self.__battery_level >= required_amount

def get_battery_level(self):
    """Public method to check the battery level."""
    return f"Current battery level: {self.__battery_level}%"

Creating and interacting with a Smartphone object

my_phone = Smartphone('Pixel', 'Pixel 5')

Installing and uninstalling apps

my_phone.install_app('WhatsApp')
my_phone.install_app('Spotify')
my_phone.uninstall_app('WhatsApp')
my_phone.show_installed_apps()

Using battery and charging

print(my_phone.get_battery_level())
my_phone.charge_phone(30)

#updated part: function: charge_phone is not defined in the class. So the code generated error message when running. I added the part below, hope it would be helpful. Thanks for your sharing.

def charge_phone(self, amount): self.__batterry_level = min(100, self.__batterry_level + amount) print(f"Battery charged to {self.__batterry_level}%")
