I would like to use the bpython interpreter for debugging. My question is similar to \"Is it possible to go into ipython from code?\", which asks about ipython.
If you
Yes, using this wrapper, which you can also access by adding the statement import bpdb
to your code. Add bpdb.set_trace()
wherever you want to break, and from the pdb
interpreter enter "B" to jump into a bpython
session with everything from the stack frame:

Your question seems perfectly valid to me!
