Runtime Error

What This Error Means

This error occurs when trying to access an attribute of an object that does not exist or is of the wrong type.

Why It Happens

This error typically happens when there's a mismatch between the type of object you're trying to access and the type of object it actually is. In this case, you're trying to access a dictionary attribute 'key' for an integer object.

How to Fix It

1. 1To fix this error, you need to ensure that the object you're trying to access is of the correct type. You can do this by checking the type of the object using the type() function or by using a try-except block to catch and handle the error. Here's an example of how to fix the code:

Example Code Solution

class Person:
    def __init__(self, name):
        self.name = name

person = Person(1)
print(person.key)

class Person:
    def __init__(self, name):
        self.name = name

person = Person(1)
if hasattr(person, 'name'):
    print(person.name)
else:
    print('Attribute does not exist')
