1. 使用`traceback.format_exc()`¹: ```python import traceback try: 1/0 except Exception: print(traceback.format_exc()) ``` 这将打印出完整的traceback。 2. 使用`sys.exc_info()`¹: ```python import sys import traceback try: 1/0 except Exception: print(sys.exc_info()[2]) `...
如果异常没有处理或捕捉,程序就会用traceback终止程序的执行,如果是在多线程程序中,则会终止当前线程的执行。 职场亮哥 2020/10/10 1.6K0 Python的异常机制 pythonexception异常 Python机制设置了异常机制。异常指的是运行时程序遇到的可以被捕捉的错误。程序捕捉了异常,而不至于让程序运行错误而crash。异常增强了程序...
在被装饰的函数中输入参数 timeout 来控制时长,异常可以用 Exception 捕获 示例代码 代码语言:javascript 代码运行次数:0 运行 AI代码解释 import stopit import time import traceback @stopit.threading_timeoutable() def infinite_loop(): # As its name says... try: print("Start") for i in range(...

(如果你尝试这样做,它实际上会以半随机的方式输出三个交错的完整traceback,然后你可能不得不以某种方式停止主进程。) API参考 multiprocessing包大部分复制线程模块的API。 multiprocessing.Process和exception Process class multiprocessing.Process(group=None, target=None, name=None, args=(), kwargs={}, *, dae...
