python 3 not detected upon execute buffer

[Ricopan]

This is similar to bug #450552.
Version: python-mode.el-6.0.3

Upon execute buffer (C-c C-c) in python interpreter:

>>> ## executing temporary file /tmp/Python4165i_k.py...
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'execfile' is not defined
>>>

M-x python3 (C-c !) starts a python 3 interpreter:

Update:

this occurs when within a virtualenv with the default python (~/my_virtual_env/bin/python) set to a local python 3.2.

Outside of virtualenv if I switch to use python 3.2 by changing py-shell-name to python3 then error does not occur.

If py-shell-name is examined to determine python3 vs python2, would be helpful to have this noted in Install.

Current trunk should display version 6.0.4, i.e. one number ahead last
release

Could you check it out and try again?

bzr branch lp:python-mode

Assume it's exists there still BTW, just let's make sure referring to.

Thanks,

Andreas

Yes, also with: Using `python-mode' version 6.0.4

I don't know if this is worth spending time on. Now that I realize I can
simply link my python to python3 in my virtualenv, and have py-shell set to
python3, I can avoid the error. Thanks for your attention.

maybe the link still in your cache?

[Andreas Roehler (a-roehler)]

with -r779

    `py-shell-name' accepts a PATH/TO/EXECUTABLE

    in addition to name of an installed default Python-Shell.
    Beside customize permits installing commands like

    (defun python-XYZ-shell (&optional argprompt)
      "Start an Python-XYZ interpreter ... "
      (interactive)
      (let ((py-shell-name "PATH/TO/PYTHON-XYZ"))
        (py-shell argprompt)))

BTW being not surprised should something to be done still in this area,
please write a new report, should you encounter an inconvenience,

closing this
