The data exploration and some quick visualizations I prefer to do in R.
I will do some data generation and machine learning in Python. I'm not familiar enough with anycodings_type-hinting pyright to know if it has a different anycodings_type-hinting preferred way of suppressing errors.These days, I am often programming in multiple different languages for my projects. To answer your other questions, your anycodings_type-hinting example program is idiomatic Python, and anycodings_type-hinting type checkers should ideally support it anycodings_type-hinting without modification.Īdding a # type: ignore comment to the anycodings_type-hinting line with the error is the PEP 484 anycodings_type-hinting sanctioned way of suppressing error anycodings_type-hinting messages.
There anycodings_type-hinting is perhaps a principled reason why anycodings_type-hinting pyright is deciding to do this that I'm anycodings_type-hinting overlooking, but IMO this seems like a anycodings_type-hinting bug. What pyright seems to do instead is to anycodings_type-hinting just "leak" the generic variable. Report an error and ask the user to specify the desired generic type.Some type checkers may attempt to do this, but I don't know of any that handles this particular case perfectly. Attempt to infer the correct type based on context.This is what pyre and pytype does - they deduce 'tmpfolder' has type 'Any' and 'nothing' respectively. Both types are a valid subtype of every type, so are guaranteed to be valid placeholders and not cause downstream errors. Pick some placeholder type like either 'Any', the dynamic type, or NoReturn (aka 'bottom' aka 'nothing').For example, mypy ends up picking 'str' by default, giving 'tmpfolder' a type of 'str'. Pick some default generic type based on the typevar, such as 'str' or 'Union'.In this case, I think there are several anycodings_type-hinting reasonable things for a type checker to anycodings_type-hinting do: However, your example code omits anycodings_type-hinting specifying the generic type, leaving it anycodings_type-hinting up to the type checker to infer anycodings_type-hinting something appropriate. In short, the anycodings_type-hinting tempfile.TemporaryDirectory class is anycodings_type-hinting typed to be generic with respect to anycodings_type-hinting AnyStr.
