gdb可以调试python的pdb么

1.如题：

gdb可以调试python的pdb么？

答案：可以，实验如下。

 

2.实验：

生成一个a.py代码文件，代码如下：

import pdb

a = 1
print "111",a
pdb.set_trace()
a = 2
print "222",a

 

gdb python

(gdb) b main
Breakpoint 1 at 0x400770: file ./Modules/python.c, line 23.
(gdb) b exit
Function "exit" not defined.
Make breakpoint pending on future shared library load? (y or [n]) y
Breakpoint 2 (exit) pending.

Breakpoint 2 (exit) pending.
(gdb) r a.py

Breakpoint 1, main (argc=2, argv=0x7fff6d9883f8) at ./Modules/python.c:23
