setting a breakpoint in the function of my module

[Jason Jiang]

Hi,

I have two modules: a.py and b.py. In a.py, I have a function called 
aFunc(). I'm calling aFunc() from b.py (of course I import module a first). 
The question is how to directly set a breakpoint in aFunc().

The way I'm doing now is to set a breakpoint in b.py at the line to call 
aFunc(), 'c' to it, then 's' to step in, then set the breakpoint inside 
aFunc() by 'b lineNumber'. It's too cumbersome.

Thanks.
Jason
