I'm not sure to get what you mean here... The condition is a Python 
*expression*. If this expressions evals to True, the bp will trigger, 
else it will be ignored.

given the code:

00: for x in range(10):
01:    y = x * 2
02:    print y

and the pdb commands:

(pdb) break 2
(pdb) condition 1 y >= 6

The bp #1 should only trigger if y >= 6

I definitively don't understand you. How does statements in your program 
relates to setting conditions on a bp in the debugger ?

Did you really bother reading the doc ? If you want to clear a given pb, 
you need to pass it's number as argument to clear.
