Introducing the Socket Python SDK
The initial version of the Socket Python SDK is now on PyPI, enabling developers to more easily interact with the Socket REST API in Python projects.
Backport Python3.8+ typing utils & issubtype & more
pip install typing_utils
Check that the left argument is a subtype of the right.
For unions, check if the type arguments of the left is a subset of the right. Also works for nested types including ForwardRefs.
Examples:
from typing_utils import issubtype
issubtype(typing.List, typing.Any) == True
issubtype(list, list) == True
issubtype(list, typing.List) == True
issubtype(list, typing.Sequence) == True
issubtype(typing.List[int], list) == True
issubtype(typing.List[typing.List], list) == True
issubtype(list, typing.List[int]) == False
issubtype(list, typing.Union[typing.Tuple, typing.Set]) == False
issubtype(typing.List[typing.List], typing.List[typing.Sequence]) == True
JSON = typing.Union[
int, float, bool, str, None, typing.Sequence["JSON"],
typing.Mapping[str, "JSON"]
]
issubtype(str, JSON, forward_refs={'JSON': JSON}) == True
issubtype(typing.Dict[str, str], JSON, forward_refs={'JSON': JSON}) == True
issubtype(typing.Dict[str, bytes], JSON, forward_refs={'JSON': JSON}) == False
Get the unsubscripted version of a type.
This supports generic types, Callable, Tuple, Union, Literal, Final and ClassVar. Return None for unsupported types.
Examples:
from typing_utils import get_origin
get_origin(Literal[42]) is Literal
get_origin(int) is None
get_origin(ClassVar[int]) is ClassVar
get_origin(Generic) is Generic
get_origin(Generic[T]) is Generic
get_origin(Union[T, int]) is Union
get_origin(List[Tuple[T, T]][int]) == list
Get type arguments with all substitutions performed.
For unions, basic simplifications used by Union constructor are performed.
Examples:
from typing_utils import get_args
get_args(Dict[str, int]) == (str, int)
get_args(int) == ()
get_args(Union[int, Union[T, int], str][int]) == (int, str)
get_args(Union[int, Tuple[T, int]][str]) == (int, Tuple[str, int])
get_args(Callable[[], T][int]) == ([], int)
Return type hints for an object.
This is often the same as obj.annotations, but it handles forward references encoded as string literals, and if necessary adds Optional[t] if a default value equal to None is set.
The argument may be a module, class, method, or function. The annotations are returned as a dictionary. For classes, annotations include also inherited members.
TypeError is raised if the argument is not of a type that can contain annotations, and an empty dictionary is returned if no annotations are present.
BEWARE -- the behavior of globalns and localns is counterintuitive (unless you are familiar with how eval() and exec() work). The search order is locals first, then globals.
If no dict arguments are passed, an attempt is made to use the globals from obj (or the respective module's globals for classes), and these are also used as the locals. If the object does not appear to have globals, an empty dictionary is used.
If one dict argument is passed, it is used for both globals and locals.
If two dict arguments are passed, they specify globals and locals, respectively.
FAQs
utils to inspect Python type annotations
We found that typing-utils demonstrated a healthy version release cadence and project activity because the last version was released less than a year ago. It has 1 open source maintainer collaborating on the project.

Security News
Floating dependency ranges in npm can introduce instability and security risks into your project by allowing unverified or incompatible versions to be installed automatically, leading to unpredictable behavior and potential conflicts.

A new Rust RFC proposes "Trusted Publishing" for Crates.io, introducing short-lived access tokens via OIDC to improve security and reduce risks associated with long-lived API tokens.
