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

二 pdb实例

E:\python\work>python -m pdb prime.py
> e:\python\work\prime.py(1)<module>()
->import math
(Pdb) list
1->import math
2def isprime(i):
3for t in range(2,int(math.sqrt(i))+1):
4if i % t ==0:
5return0
6else:
7return1
8
9print('100到110之间的素数为：')
10for i in range(100,110):
11if isprime(i):
(Pdb) l 12,15
12print(i)

15
(Pdb) b 12
Breakpoint1 at e:\python\work\prime.py:12
(Pdb) b 7
Breakpoint2 at e:\python\work\prime.py:7
(Pdb) c
100到110之间的素数为：
> e:\python\work\prime.py(7)isprime()
->return1
(Pdb) c

->print(i)

->if isprime(i):

->for i in range(100,110):

> e:\python\work\prime.py(11)<module>()
->if isprime(i):

(Pdb) cl
Clear all breaks? y
