[issue42524] pdb access to return value

[Irit Katriel]

Irit Katriel  added the comment:

It actually is in the locals, and it's called __return__. So you can access it 
with 

locals()['__return__']

I'll try to see where that can be documented.

[issue42524] pdb access to return value

[Romuald Brunet]

New submission from Romuald Brunet :

When using the pdb module, there is currently no way to easy access the current 
return value of the stack

This return value is accessed by the 'retval command'

I propose using the currently unused argument to allow storing the return value 
in the local variables, accessible via the debugger

For example:


def foo():
debugger()
return ComplexObject()

def bar():
return foo()

(pdb) retval

(pdb) retval zz
(pdb) zz.attribute
'some value'
