Jupyterlab alternative for pdb/ipdb

Question

How can I set a breakpoint in a Python script running in a Jupyter notebook such that:

• When the breakpoint is hit, the variables from the script are available in the Jupyter kernel.
• I can interact with and modify those variables in the Jupyter notebook during the pause.
• After resuming execution, the changes I made in the notebook are reflected in the script's state.

The typical import ipdb; ipdb.set_trace() approach doesn't allow direct synchronization of the kernel's namespace with the script. Is there an alternative that provides this functionality?
