any() — Advanced Examples

Returns True if at least one element in an iterable is truthy

any() protocol implementation

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

python

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

obj = Custom()
print(any(obj))

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

Handling unusual inputs and edge cases.

python

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

# Type checking
print(type(42))

Knowing these edge cases prevents subtle bugs in production.
