Issue 33594: add deprecation since 3.5 for a few methods of inspect. (original) (raw)

inspect's getargspec, as well as Signature's from_function, and from_builtin are deprecated.

They all emits DeprecationWarning but:

The deprecation warning does not say since which version since are deprecated. For the two Signature's methods, there is no documentation available, so finding this information is difficult.

Many tool rely on introspection to provide object help via docstring, which also did not include this deprecation notice.

Adding the deprecation informations to these 3 function/methods would be good to foster migration to newer ways.
