how to type python API responses similar to TS `as`?
I'm using a lib that types its response as
-> (Unknown | Response | Any)
If i know/expect the response to be a Response and that is has an id field,
how can I cast that in my code?
Typescript provides an as <type> operator for this.
response = self.client.get_user(username=username)
user_id = response.data['id']
Cannot access member "data" for type "Response"
Member "data" is unknownPylancereportGeneralTypeIssues
in addition to the typing.cast I'm looking for a simple way to define the shape of a response, without adding a full class hierarchy just to type a blob of data coming back from a third party API.
Similar to type or even interface in typescript.
It seems the Response object/class isn't typed.
Solution
You're looking for typing.cast
response = cast(Response, self.client.get_user(username=username))
user_id = response.data['id']
