PDB - stepping out of a function

Question

Can I step out of a function after stepping into it with step while using pdb / ipdb debugger?

And if there's no such option - what is the fastest way to get out of the stepped-in function?

Answer 1

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.

r then n, got it! – Oxidase

And you can use retval debugger command to examine the return value. – Corbitt

Answer 2

step will continue the execution. To move up and down the callstack, you can use up (move up to the calling function), and then down to go back the other way.

Have a look at the doc: https://docs.python.org/3.6/library/pdb.html#pdbcommand-step

I would like to continue the execution until the current running function (the one I stepped into) is finished, something like until does for loops – Heresy

well, the doc quite clearly list r(eturn) which does exactly what you are asking for – Edibles

That's the solution I was looking for. Thought r(eturn) is just a synonym to a regular return! – Heresy

You might want to edit or delete this answer, because it currently doesn't answer the (since edited) question as asked – Numberless

Answer 3

You can just add a breakpoint outside the function and continue until you reach it. For example, if the call to your function is at line 14, you can:

(Pdb) b 15
(Pdb) c
