slice() — Advanced Examples

Creates a slice object for use in extended indexing

slice() protocol implementation

Implementing the protocol that slice() uses under the hood.

python

# slice() - implementing the protocol
class Custom:
    def __slice__(self):
        return "custom result"

obj = Custom()
print(slice(obj))

Understanding the dunder methods that slice() calls helps you customize behavior for your own classes.

Handling unusual inputs and edge cases.

python

# slice() edge cases
print("Edge case handling for slice()")

# Type checking
print(type(42))

Knowing these edge cases prevents subtle bugs in production.
