Xavier de Gaye added the comment: The runcode() method of InteractiveInterpreter in code.py uses the 'self.locals' dictionary as the 'globals' parameter of the invoked exec() function. And the do_interact() method of Pdb instantiates InteractiveInterpreter with 'locals' as a merge of the curre

Jurko Gospodnetić added the comment: Just ran into this problem and it's so 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

Georg Brandl added the comment: Your failure appears to be not pasted from an interpreter session; the actual failure is: (Pdb) all(x < limit for x in items) *** NameError: global name 'limit' is not defined (i.e. "limit" is not found, not "items"). This actually does not work in Python 2 ei

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

New submission from Kay: Using generators in pdb are very handy but since Python3 they don't work properly. For example: import pdb def foo(): items = [1, 2, 3] limit = 5 pdb.set_trace() foo() in pdb prompt the following fails: (pdf) all(x < limit for x in items) *** NameError: global
