Typhinting as art in Python

 Lets look at the get method of requests library. 

def get(

    url: str | bytes,

    params: _Params | None = ...,

    *,

    data: _Data | None = ...,

    headers: _HeadersMapping | None = ...,

    cookies: RequestsCookieJar | _TextMapping | None = ...,

    files: _Files | None = ...,

    auth: _Auth | None = ...,

    timeout: _Timeout | None = ...,

    allow_redirects: bool = ...,

    proxies: _TextMapping | None = ...,

    hooks: _HooksInput | None = ...,

    stream: bool | None = ...,

    verify: _Verify | None = ...,

    cert: _Cert | None = ...,

    json: Any | None = ...,

) -> Response:

Do you notice how the parameters are typehinted? 

Example: 

    params: _Params | None = ...,

In this case literally a whole sentence is hidden behind this typehint.

The developers say "For the param you need to provide a datatype similar to Params class (which is a Python Type Annotation class), or, don't provide anything at all, and in that case the param will be reassigned inside of the method".
