As mentioned by Arthur in a comment, you can use r(eturn)
to run execution to the end of the current function and then stop, which almost steps out of the current function. Then enter n(ext)
once to complete the step out, returning to the caller.
Documentation is here.
(Pdb) ?r
r(eturn)
Continue execution until the current function returns.
