Python debugger

[Guillermo Fernandez]

Hi,

I'm trying to play with the python debugger. The idea is to put lines in the 
code to automatically define breakpoints at the starting of the debugger.

(like:

1 def a():
2 #--- break
3     print 'done'

would automatically insert a break in the line number 2)

I did the code appended (I'm still quite a beginner...) but it makes me problems.
Traceback (most recent call last):
   File "C:\Python23\lib\site-packages\sm\scriptutils.py", line 52, in run
     sdb.run('exec codeObject in mainDict', locals(), mainDict)
   File "C:\Python23\lib\site-packages\sm\spedb.py", line 29, in run
     Sdb().run(statement, globals, locals)
   File "C:\Python23\lib\site-packages\sm\spedb.py", line 23, in run
     pdb.Pdb.do_break(self, str(linenbr))
   File "C:\Python23\lib\pdb.py", line 262, in do_break
     filename = self.defaultFile()
   File "C:\Python23\lib\pdb.py", line 278, in defaultFile
     filename = self.curframe.f_code.co_filename
AttributeError: Sdb instance has no attribute 'curframe'
Exception raised while running script  <source>

I run the program as:
import spedb
mainDict=__main__.__dict__
# mainDict can also be another argument passed,
# I think it's also locals() by default
mainDict['codeObject']=codeObject
spedb.run('exec codeObject in mainDict', locals(), mainDict)


I think it's because the breakpoint it's instaured before the run, but I really 
don't know how to put the breakpoint "inside" the run.

Furthermore, if I define the method run like:
     def run(self, statement, globals, locals):
         bdb.Bdb.run(self, statement, globals, locals)
it does not even prompt the usual prompt (not any prompt at all...)!
I got this:
 >>> Running 'C:\Python23\Lib\site-packages\sm\spedb.py' ...
Script '<source>' returned exit code 0

Could someone give me a hint about:
1) Why it does not work?
2) How to modify it the way I want?

Thanks a lot.
