python thread dump

一直希望python也有类似java dump的功能，上网找了一段代码可以实现类似效果：

def stacktraces():
    code = []
    import sys
    import traceback

    for threadId, stack in sys._current_frames().items():
        code.append("# ThreadID: %s" % threadId)
        for filename, lineno, name, line in traceback.extract_stack(stack):
            code.append('File: "%s", line %d, in %s' % (filename, lineno, name))
            if line:
                code.append("  %s" % (line.strip()))

    return "<br>".join(code)
