Question

The following Code (or Customs Solutions from 更妥善地在沙捞法中标注吗? 或使用inspect的解决方案。

import logging, sys

logging.basicConfig(stream=sys.stdout, level=logging.DEBUG)
logger = logging.getLogger()

def log(func):
    def logged(*args, **kwargs):
        logger.info(f"{func.__name__} starting with {args=} {kwargs=}...")
        result = func(*args, **kwargs)
        logger.info(f"{func.__name__} finished.")
        return result
    return logged

class A:
    @log
    def foo(self, x, y):
        pass

    @log
    def bar(self, x, y):
        1/0

a = A()
a.foo(2, y=3)
a.bar(2, y=3)

产出:

INFO:root:foo starting with args=(<__main__.A object at 0x0000000002784EE0>, 2) kwargs={ y : 3}...
INFO:root:foo finished.
INFO:root:bar starting with args=(<__main__.A object at 0x0000000002784EE0>, 2) kwargs={ y : 3}...
...

现有沙丘版本中是否有内在解决办法(要么在logging上,要么在另一个模块中)?

There is no @log-like decorator in Python 3.12.1 s logging module

我通过伐木源代码和测试代码来研究,并看看任何功能,这些功能使得能够确定标识方法的任何类型,我也没有发现在伐木模块测试中测试任何类型的腐蚀物的任何测试。
