bpdb

To enable bpython support within pdb, start pdb with the following code:

import bpdb
bpdb.set_trace()

This will drop you into bpdb instead of pdb, which works exactly like pdb except that you can additionally start bpython at the current stack frame by issuing the command Bpython or B.

You can exit bpython with ^d to return to bpdb.
