Retrieves the next item from an async iterator
anext() performance and internals
Performance characteristics and CPython implementation details.
python
# anext() internals import dis def using_anext(): pass # Bytecode analysis dis.dis(using_anext) # Check if it's truly built-in import builtins print(f"\nanext is builtin: {hasattr(builtins, 'anext')}") print(f"Type: {type(builtins.anext)}")
Understanding the internal implementation helps optimize hot paths in performance-critical code.
