traceback.print_stack()函数默认会将调用堆栈信息打印到标准输出。如果我们想要将调用堆栈信息作为字符串获取并用于自定义目的,我们可以使用traceback.format_stack()函数。 下面是一个示例代码: importtracebackdeffunction_c():print("Formatting current call stack:")stack_t
使用traceback.print_stack()函数可以直接打印当前的堆栈信息。这个函数会输出调用栈的每一帧,包括文件名、行号和函数名。 python def print_current_stack(): traceback.print_stack() 格式化调用栈信息为可读的字符串: 如果你想要将调用栈信息作为字符串获取,而不是直接打印,可以使用traceback.format_stack()函数。
