cpython-lru_cache-weakref: Python/asdl.c annotate

annotate Python/asdl.c @ 53787:c6376d3fa968

Issue #5920: Changed format.__float__ and complex.__float__ to use a precision of 12 when using the empty presentation type. This more closely matches str()'s behavior and reduces surprises when adding alignment flags to an empty format string. Patch by Mark Dickinson.
