[issue21161] list comprehensions don't see local variables in pdb in python3

[Jurko Gospodnetić]

Jurko Gospodnetić added the comment:

Just ran into this problem and it's sooooo uncomfortable
researching dynamic structures at run-time using PDB
without this. :-(

As a workaround, you can use a trick similar to this one
to 'import' your locals into the list comprehension body:

[l['r'](x) for l in (locals(),) for x in l['some_local']]

assuming 'r' & 'some_local' are two local variables in
your surrounding scope.

Ugly, but at least it can be made/forced to work if needed...

Best regards,
