Common Mistakes

Using name which is undefined here.

Using self.new_name which is not correct.

The method should assign the parameter new_name to the instance variable self.name.

    def __init__(self, name, active):
        self.name = name
        self.active = active
    
    def status(self):
        if self.active [1] True:
            return '[2] is active'

💡 Hint

Common Mistakes

Using != which reverses the condition.

Using User instead of self.name in the message.

The method compares self.active to True using ==. It returns a message using self.name.

Complete the code to implement a method that returns a dictionary with the user's name and active status if active.

LLD

class User:
    def __init__(self, name, active):
        self.name = name
        self.active = active
    
    def info(self):
        if self.active:
            return {'name': [1], 'active': self.active}
        else:
            return None
