Summary: execfile anomaly with "from __future__ import division"
Initial Comment:
If I have a file init.py with two lines:
from __future__ import division
print 3/4
and I do
[EMAIL PROTECTED] tests]$ python
Python 2.4 (#1, Feb 16 2005, 01:23:25)
[GCC 3.4.3 (Mandrakelinux 10.0 3.4.3-2mdk)] on linux2
Type "help", "copyright", "credits" or "license" for
more information.
>>> execfile('init.py')
0.75
>>> 3/4
0
I would have expected the latter to return 0.75 as
well.
Due to this it seems impossible to provide init code
that would initialize the interactive prompt to
future division behaviour.
The same applies to exec statement.
I'm not sure if this is bug, or an unfortunate
feature. The documention is not very clear on this
issue.
