python的pdb调试命令的命令整理及实例
一、命令整理
| 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 |
