问题 If a file myfile.py contains: class A(object): # Some implementation class B (object): # Some implementation How can I define a method so that, given myfile.py , it returns [A, B]? 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?

由 家住魔仙堡 提交于 2019-12-21 03:11:02
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

Can't get argspec for Python callables?

由 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
