Xavier de Gaye added the comment: The NameError exception occuring on a generator expression referencing a local variable when the generator is called within exec() is the object of multiple entries in the bug tracker, see issue 13557. msg 149096 in this issue suggests using exec(code,

Xavier de Gaye added the comment: FWIW this generator expression can be evaluated with the 'interact' command: --Return-- /test/comprehension.py(5)foo()-None - pdb.set_trace() (Pdb) interact *interactive* all(x limit for x in items) True (Pdb) -- nosy: +xdegaye

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

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

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

[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

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
