这样，每次调用fmt.Scanf都会正确地阻塞并等待用户输入，从而避免了之前观察到的异常行为。
示例代码： #include <sys/stat.h> #include <iostream> #include <ctime> void getLinuxFileInfo(const char* filename) {     struct stat buffer;     if (stat(filename, &buffer) == 0) {         std::cout << "文件大小: " << buffer.st_size << " 字节\n";         std::time_t mtime = buffer.st_mtime;         std::cout << "修改时间: " << std::asctime(std::localtime(&mtime));     } else {         std::cout << "无法访问文件\n";     } } 基本上就这些方法。
exact=False参数允许to_datetime在尝试解析日期时忽略字符串中的额外数据，只要日期部分能够被识别。
直接使用简单的字符串分割或替换操作往往无法满足需求，甚至可能导致数据丢失或格式错误。
sys模块提供了sys.path.insert()方法，允许我们在sys.path列表的指定位置插入新的路径。
定期查看主机控制面板提供的资源使用报告，了解你的网站是否经常达到CPU或内存限制。
