The Ultimate Guide to Python Programming With Python 3.10 - Class __repr__

The video tutorial explains how to implement and customize the __repr__ method in Python. It begins by discussing built-in methods and the significance of the __repr__ method for object representation. The tutorial then demonstrates how to define a custom __repr__ method in a Python class using VS Code. Finally, it shows how to test the custom representation by running the Python file in interactive mode and inspecting the output.

What is the purpose of the __repr__ method in Python?

• To initialize an object

• To delete an object

• To represent an object as a string

• To execute a function

How can you define a custom __repr__ method in a Python class?

• By using the __del__ method

• By defining a method named __repr__ with two underscores on each side

• By using the __str__ method

• By using the __init__ method

What parameters does the custom __repr__ method typically take?

• args

• cls

• self

• kwargs

What is the output when you print an object with a custom __repr__ method?

• An error message

• A formatted string defined in the __repr__ method

• The default string representation

• The memory location of the object

What happens if you don't define a __repr__ method in your class?

• The object cannot be printed

• Python uses a default representation showing the memory address

• The object is automatically deleted

• The object is converted to a string
