[issue32315] can't run any scripts with 2.7.x, 32 and 64-bit

[Martin]

New submission from Martin :

When I try to run a really simple script like:
def fun(a):
print a
return

I get this error:

Exception in Tkinter callback
Traceback (most recent call last):
  File "C:\Python27\lib\lib-tk\Tkinter.py", line 1541, in __call__
return self.func(*args)
  File "C:\Python27\lib\idlelib\MultiCall.py", line 166, in handler
r = l[i](event)
  File "C:\Python27\lib\idlelib\ScriptBinding.py", line 149, in run_module_event

if PyShell.use_subprocess:
AttributeError: 'module' object has no attribute 'use_subprocess'

It basically means Python is only usable by copy-pasting code into Shell, any 
kind of script fails with that error.

Your posted code and much else runs fine for me with 2.7.14 on Win 10. Millions 
of lines of legal Python code run on perhaps a million machines aroung the 
world.  Except possibly for your particular machine, your conclusion is wrong.

>From the traceback, you are running code via IDLE, most likely from the 
>editor.  Please specify exactly what you do to get the error, starting with 
>which 2.7.z patch release you are using.

When current Python and IDLE are correctly installed, PyShell.use_subprocess is 
set to True nearly first thing on startup.  If one starts IDLE with the '-n' 
option, use_subprocess is set to False.  The variable is never deleted.

This is the first report I know of where Python sees use_subprocess as missing. 
 Why?  I can think of the following possibilities of what might be wrong on 
your machine:
* Your python installation has a severe bug. If you need help with 
re-installing, try the python-list mailing list.
* Hardware bug.  See a tech.
* You are using an obsolete version of 2.7 and ran into a bug since fixed.  
Upgrade to 2.7.14.
* You have MacOS and ignored https://www.python.org/download/mac/tcltk/.  Click 
Help and About IDLE and the box will include the tcl/tk version being run.  
Follow the instruction very carefully.

None of the above are in scope for this tracker.

* You somehow triggered a severe super-obscure bug. If you convince me that 
there might plausibly be a bug in IDLE, and agree to help investigate, I will 
try to find and fix it.

For a start, run "python -m test" on a terminal or command line, where 'python' 
is the specific command to run 2.7 on your OS.

I used Python on other machines, I know how it's supposed to work. I'm using 
Windows 7 and this problem happened with 2.7.14, 2.7.13 and 2.7.9. I didn't 
bother trying all other versions because it looked like it didn't matter what 
version it was. For every version, I was running scripts with PyShell file (59 
KB) from idlelib.

I found another two files called "idle" in idlelib, one with and other without 
console. Either of those when ran starts Shell window and I can run scripts 
perfectly fine from there. 

I don't know what the problem is with PyShell file, but since with idle files 
it works as expected, I won't chase the cause of this.
