That comes from how the code object was compiled:
>>> code = compile('error','Anything you want goes here','single')
>>> exec code
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "Anything you want goes here", line 1, in ?
NameError: name 'error' is not defined
For example, in ipython:
In [1]: error
---------------------------------------------------------------------------
exceptions.NameError Traceback (most recent
call last)
/home/fperez/<ipython console>
NameError: name 'error' is not defined
So any regexp-matching based approach here is likely to be fairly brittle,
unless you restrict your tool to the standard python interpreter, and you
get some guarantee that it will always tag interactive code with
'<string>'.
