bytes() — Advanced Examples

Creates an immutable sequence of bytes

bytes() protocol implementation

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

python

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

obj = Custom()
print(bytes(obj))

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

Handling unusual inputs and edge cases.

python

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

# Type checking
print(type(42))

Knowing these edge cases prevents subtle bugs in production.
