python pdb调试以及sublime3快捷键设置
pdb调试
如果对gdb比较熟悉的话，pdb就很容易上手。以一个demo快速了解常用的调试命令。
def test(a):
while True:
if a > 10:
break
a += 1
return a
if __name__ == '__main__':
test(1)
- python -m pdb test.py进入调试环境
- b test
在test函数处设置断点，断点号为1
(Pdb) b test
Breakpoint 1 at f:\python\pdb\test.py:1
- b 2
在第二行设置断点，断点号为2
(Pdb) b 2
Breakpoint 2 at f:\python\pdb\test.py:2
- condition 2 a7
在2号断点处设置条件 a7 - b
显示所有断点信息
(Pdb) b
Num Type Disp Enb Where
1 breakpoint keep yes at f:\python\pdb\test.py:1
2 breakpoint keep yes at f:\python\pdb\test.py:2
stop only if a==7
- cl 1
去除1号断点，只有cl删除所有断点
(Pdb) cl 1
Deleted breakpoint 1
- n
单步跟踪，不进入函数
(Pdb) n
> f:\python\pdb\test.py(8)<module>()
-> if __name__ == '__main__':
(Pdb) n
> f:\python\pdb\test.py(9)<module>()
-> test(1)
- s
单步跟踪，进入函数
(Pdb) s
--Call--
> f:\python\pdb\test.py(1)test()
-> def test(a):
- c
继续运行在 a==7 条件断点处停止 - p a
此时，打印a的值为7
(Pdb) c
> f:\python\pdb\test.py(2)test()
-> while True:
(Pdb) p a
7
- a
打印所在函数参数
(Pdb) a
a = 7
- l
查看运行到某处代码
(Pdb) l
1 def test(a):
2 B-> while True:
3 if a > 10:
4 break
5 a += 1
6 return a
7 if __name__ == '__main__':
8 test(1)
[EOF]
- quit
退出
sublime设置
sublime设置快捷键F5为运行，Ctrl+F5调试。就会对python调试方便很多。
- Package Control中下载SublimeREPL(Read-Eval-Print-Loop)
- Preferneces -> Key Bingdings-User进行设置
