py-traceback-line-re is what matches those lines.  It's current
definition is

(defconst py-traceback-line-re
  "[ \t]+File \"\\([^\"]+\\)\", line \\([0-9]+\\)"
  "Regular expression that describes tracebacks.")

There are probably also gud.el (and maybe compile.el) regexps that
need to be changed too.  I'd rather see something that outputs the
same regardless of whether it's a real file, or something "fake".
Something like

Line 1 of <stdin>
Line 12 of foo.py

should be fine.  I'm not crazy about something like

File "foo.py", line 12
In <stdin>, line 1
