How to ignore string when using pdb?

For some quick Python debugging, I sometimes enter a line import pdb;pdb.set_trace()that will put me in the debugger. Very comfortably. However, if I want to debug a cycle that can run many, many, many times, it loses its effectiveness somewhat. I could crush continue many, many, many times, but is there a way to remove / ignore this hard-coded breakpoint so I can finish it?

I can set the global flag and run it conditionally, but then I will lose the "autonomy" of the single-line breakpoint, also requiring one more flag for each pdb.set_trace().
