Re: [Python-ideas] Dataclasses, keyword args, and inheritance

It may be possible but it makes for pretty leaky abstractions and it's unclear what that custom __init__ should look like. How am I supposed to know what the replacement for default_factory is? Moreover, suppose I want one base class with an optional argument and a half dozen subclasses each with

[Python-ideas] Non-intrusive debug logging

Everyone uses logging during code development to help in debugging. Whether using a logging module or plain old print statements, this usually requires introducing one or (many) more lines of code into the model being worked on, making the existing, functional code more difficult to read. It

Re: [Python-ideas] Dataclasses, keyword args, and inheritance

It is possible to pass init=False to the decorator on the subclass (and supply your own custom __init__, if necessary): @dataclass class Foo: some_default: dict = field(default_factory=dict) @dataclass(init=False) # This works class Bar(Foo): other_field: int -- Ivan On 23 January

Re: [Python-ideas] Preemptive multitasking and asyncio

If I'm understanding correctly, the interpreter already does this with threads. About every 15 milliseconds the interpreter will stop a thread and see if there are any others to work on, see "Grok the GIL," blog: https://emptysqua.re/blog/grok-the-gil-fast-thread-safe-python/ or the PyCon talk:

[Python-ideas] Preemptive multitasking and asyncio

I found a question and answer at Stackoverflow[1] which says that asyncio/await is like cooperative multitasking. My whish is to have preemptive multitasking: The interpreter does the yielding. The software developer does not need to insert async/await keywords into its source code any more.
