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 |
