[New-bugs-announce] [issue26627] IDLE incorrectly labeling error as internal

[Tadhg McDonald-Jensen]

New submission from Tadhg McDonald-Jensen:

(I apologize if I'm doing something wrong)

When using a file named run.py in idle, any errors raised from the module makes IDLE show a traceback like this:

Traceback (most recent call last):
** IDLE Internal Exception: 
  File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/idlelib/run.py", line 351, in runcode
    exec(code, self.locals)
  File "/Users/Tadhg/Documents/run.py", line 1, in <module>
    raise ValueError
ValueError

I looked into idlelib.run and think the culprit is the way print_exception tries to exclude internal files, specifically line 180 in vs 2.7 and line 206 in vs3.5

            exclude = ("run.py", "rpc.py", "threading.py", "queue.py",
                       "RemoteDebugger.py", "bdb.py")

this excludes paths with these names anywhere in the path (later in cleanup_traceback) instead of getting the absolute paths of these modules.
