The discussion about niladic functions, made me want to follow a segue and do some reflection/introspective programming in Python. I’ve not done a lot of that yet, and it seemed like an educational (well, at least entertaining) goose chase.
If I run the following code: import datetime datetime.datetime.now(13, 42) I will get an error (expected). The error I will get is: Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: now() takes at most 1 argument (2 given) So, at some point, there’s some metadata in the system attached to the builtin datetime.datetime.now method, that indicates 1 argument, tops. So here’s my basic question. Is there anyway to programatically query that information in python code? inspect.signature(datetime.datetime.now) just gives a ValueError. inspect must only be good for the python code that I write, in python. Is there another way to dig out what the interpreter knows there? -- https://mail.python.org/mailman/listinfo/python-list
