Terry J. Reedy added the comment:

#6858 was the issue I referred to.
Recognizing #!...python, common on *nex, which the patch does not do, seems 
sensible.  I thought about coding line, but general idea is not specific to 
python.

No. When I try to open the file a small window entitled Specify file encoding 
pops up that says 
The file's encoding is invalid in Python 3.x.
Idle will convert it to UTF-8.
What is the current encoding of the file?
followed by an entry widget that has cp1252 and ok and cancel buttons. 
When I click ok the computer go dunnn and a error window titled Decoding 
Error that says File C:\Python32\misc\bee.jpg Failed to Decode with an ok 
button which, when clicked, closes idle (the edit window, not the shell). Does 
that answer your question?

I am also somewhat puzzled by this issue.
The other day I was able to open some .txt files just to see if I could and 
they opened just fine.
Just now I tryed to open a .jpg file and I got an error message, but then 
again, why would someone save a python file as a jpeg image?

Is the error message a traceback? If so, could you open a separate issue for it?

This is related to issue6858. I assume that the point of this issue is to 
enable syntax highlighting by relying on the Windows registry?

Terry J. Reedy tjre...@udel.edu added the comment:

I am a little puzzled by this issue.
1. Why would a Windows user use any extention other than .py or .pyw, which 
IDLE opens fine. How many people do something senseless like hand-registering, 
say 'xiq', as a python file?
2. .pyc files are binary files and NOT source code files and cannot be opened 
by IDLE as it will attempt to decode them into text. So why the check for that?

Also, I believe there is another issue to add a 'Treat this as Python code' 
entry to one of the menus. This would cover the case of files without 
extensions and files that are not python files but happen (on a case-by-case 
basis) to have python code embedded within.

So I am thinking that this should be closed.

This makes sense, but the code should:
- not make the query when the extension is empty
- catch the WindowsError raised when the extension is not in the registry.

[issue6804] IDLE: Detect Python files even if name doesn't end in .py

[Gabriel Genellina]

New submission from Gabriel Genellina gagsl-...@yahoo.com.ar:

A Python source file name doesn't necesarily end 
in .py/.pyw; on Linux, scripts usually have no 
extension but are recognized by its shebang line. 
Windows uses file type associations: .py files are of 
type Python.File, and .pyc files are Python.NoConFile.

This patch makes IDLE recognize as a Python source 
(and colorize) any file of those types, regardless of 
extension.
