Breaking at a member function in the Python debugger (1 answer)

Closed 8 years ago.

我使用了“类别名称:功能”或“类别名称:功能”和“工作”等。现在,我把“双线”作为工作。但随着我经常修改我的法典,直线变化。因此,如何在金星上打破班级成员的职能? 我看着它和安普;阅读了花on手,没有直接答案。感谢!

Answer 1

在pdb、Sharma debugger>上,可以确定休息点。

b classname.methodname

after the class definition has been parsed.

例如,

% pdb ~/pybin/test.py

> /home/unutbu/pybin/test.py(4)<module>()
-> class Foo(object):
(Pdb) l
  1     #!/usr/bin/env python
  2     # coding: utf-8
  3     
  4  -> class Foo(object):
  5         def bar(self): pass
  6     
  7     foo=Foo()
  8     foo.bar()
[EOF]

在课堂上课前设置休息点失败:

(Pdb) b Foo.bar
*** The specified object  Foo.bar  is not a function
or was not found along sys.path.

but after parsing the class:

(Pdb) n
> /home/unutbu/pybin/test.py(7)<module>()
-> foo=Foo()
(Pdb) l
  2     # coding: utf-8
  3     
  4     class Foo(object):
  5         def bar(self): pass
  6     
  7  -> foo=Foo()
  8     foo.bar()
[EOF]

规定休息点工作:

(Pdb) b Foo.bar
Breakpoint 1 at /home/unutbu/pybin/test.py:5
(Pdb) 

(Pdb) r
> /home/unutbu/pybin/test.py(5)bar()
-> def bar(self): pass

在你想要打破的界线上,如果存在一个持续裂痕,你也可以使用:

import pdb; pdb.set_trace()

见python doc。
