aiter() — Advanced Examples

Returns an asynchronous iterator from an async iterable

aiter() protocol implementation

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

python

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

obj = Custom()
print(aiter(obj))

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

Handling unusual inputs and edge cases.

python

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

# Type checking
print(type(42))

Knowing these edge cases prevents subtle bugs in production.
