python的pdb调试命令的命令整理及实例

一、命令整理

二 pdb实例

> e:pythonworkprime.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

9print('100到110之间的素数为：')
10for i in range(100,110):
11if isprime(i):
(Pdb) l 12,15

(Pdb) b 12
Breakpoint1 at e:pythonworkprime.py:12
(Pdb) b 7

(Pdb) c
100到110之间的素数为：
