Here, the returned values for A and B can be either the name of the classes or the type of the classes. (i.e. type(A) = type(str) or type(A) = type(type)) 回答1: You can get both: import importlib, inspect for name, cls in inspect.getmembers(importlib.import_module("myfile"), inspect.isclass): you may additionally

How do I get the value and type of the current exception in C++ using gdb?

问题 gdb allows one to catch exceptions when they're thrown, and when they're caught. But sometimes the line an exception is thrown has no symbols, or a breakpoint is triggered during exception handling. How do I inspect the value of the current exception? 回答1: Earlier answers were correct when written (in 2013), but since then gdb and libstdc++ have changed. libstdc++ now has some hooks that let gdb interact more nicely with the exception system. In particular, there is now enough information

问题 I'm trying to load JSON back into an object. The "loads" method seems to work without error, but the object doesn't seem to have the properties I expect. How can I go about examining/inspecting the object that I have (this is web-based code). results = {"Subscriber": {"firstname": "Neal", "lastname": "Walters"}} subscriber = json.loads(results) for item in inspect.getmembers(subscriber): self.response.out.write("<BR>Item") for subitem in item: self.response.out.write("<BR> SubItem=" + subitem

Can't get argspec for Python callables?

我怕爱的太早我们不能终老 提交于 2019-12-06 18:31:57
问题 I'm playing with Python callable. Basically you can define a python class and implement __call__ method to make the instance of this class callable. e.g., class AwesomeFunction(object): def __call__(self, a, b): return a+b Module inspect has a function getargspec, which gives you the argument specification of a function. However, it seems I cannot use it on a callable object: fn = AwesomeFunction() import inspect inspect.getargspec(fn) Unfortunately, I got a TypeError: Traceback (most recent
