bytearray() protocol implementation

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

python
# bytearray() - implementing the protocol
class Custom:
    def __bytearray__(self):
        return "custom result"

obj = Custom()
print(bytearray(obj))

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

Edge cases with bytearray()

Handling unusual inputs and edge cases.

python
# bytearray() edge cases
print("Edge case handling for bytearray()")

# Type checking
print(type(42))

Knowing these edge cases prevents subtle bugs in production.
