[issue40507] FileNotFound error raised by os.exec* doesn't contain filename

[Tal Einat]

Tal Einat  added the comment:

After further reading, especially the docs for OSError which describe the 
filename and filename2 attributes, I agree that setting .filename on the 
FileNotFoundError exception is the way to go.

I agree that having the error message include the executable name could be 
useful.

FileNotFoundError: [Errno 2] No such file or directory
>>> print(sys.last_value.filename)
