从Python 3.6开始,CPython 支持构建带有嵌入式 “标记”(探测器)的版本,借助 DTrace 或 SystemTap 脚本,开发者能够更轻松地监视系统上 CPython 进程的运行状态 。不过需要注意的是,DTrace 标记属于 CPython 解释器的实现细节,在不同 CPython 版本之间,探针兼容性无法得到保证,版本变更时 DTrace 脚本可能会失效。

Python提供了一个内置的模块traceback,可以用来打印堆栈信息。通过使用traceback.format_stack()函数,我们可以获取当前堆栈信息并将其以字符串的形式返回。下面是一个简单的示例: importtracebackdeffoo():bar()defbar():print(traceback.format_stack())foo() ...
