在配置VSCode中的Python开发环境时,首要步骤是创建并配置launch.json文件与tasks.json文件。在launch.json中,需要配置program、实际gdb的路径以及预运行任务"xx"。"xx"代表在调试前执行的任务,例如可以是编译或构建程序。在tasks.json中,需要将label设置为"xx"。例如设置为"debug"。完成配置后,即可通过 ...
另一种分析代码的方法是使用cProfile.run()函数,它比简单的 time.time() 技术提供了更多的细节信息。cProfile.run()函数在docs.python.org/3/library/profile.html中解释。 来自time.time()的返回值是有用的,但是不可读。time.ctime()函数返回当前时间的字符串描述。您也可以选择传递从 Unix 纪元以来的秒数,...
