The Ultimate Guide to Python Programming With Python 3.10 - __getitem__() and __setitem__()

The video tutorial explains how to implement dict slicing in Python by using special methods like __getitem__ and __setitem__. It demonstrates how to retrieve and set attribute values using these methods, allowing custom classes to support dict-like syntax for accessing and modifying attributes.

What is the primary reason classes in Python do not support dict slicing by default?

• Python classes cannot store key-value pairs.

• The syntax for dict slicing is not inherently supported by classes.

• Dict slicing is a feature exclusive to dictionaries.

• Classes in Python are not designed to handle string attributes.

Which special method is used to enable dict-like access to object attributes?

• __delitem__

• __init__

• __setattr__

• __getitem__

What does the __getitem__ method require as parameters?

• key and value

• self and attribute

• self and value

• self and key

How does the __setitem__ method differ from __getitem__?

• It does not interact with object attributes.

• It requires an additional value parameter to set the attribute.

• It is used to delete attributes.

• It only requires the key parameter.

What is the result of using the __setitem__ method on an ebook's title?

• An error is raised.

• The title is removed from the ebook.

• The title remains unchanged.

• The title is updated to the new value provided.
