python的pdb调试命令的命令整理及实例

一、命令整理

pdb调试命令 完整命令 简写命令 描述 args a 打印当前函数的参数 break b 设置断点 clear cl 清除断点 condition 无 设置条件断点 continue c或者cont 继续运行，知道遇到断点或者脚本结束 disable 无 禁用断点 enable 无 启用断点 help h 查看pdb帮助 ignore 无 忽略断点 jump j 跳转到指定行数运行 list l 列出脚本清单 next n 执行下条语句，遇到函数不进入其内部 p p 打印变量值，也可以用print quit q 退出 pdb return r 一直运行到函数返回 tbreak 无 设置临时断点，断点只中断一次 step s 执行下一条语句，遇到函数进入其内部 where w 查看所在的位置 ! 无 在pdb中执行语句
