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 a==7
在2号断点处设置条件 a==7

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)()
-> if __name__ == '__main__':
(Pdb) n 
> f:\python\pdb\test.py(9)()
-> 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
