Hi Alan,

from within geany.

The first line is either

#!/usr/bin/python

or

#!/usr/bin/python3

rick at rick-desktop:~$ file /usr/bin/python
/usr/bin/python: symbolic link to `python2.6'
rick at rick-desktop:~$ file /usr/bin/python3
/usr/bin/python3: symbolic link to `python3.1'


I just think it odd that there is one behaviour in an interactive
session, and a different behaviour when run from a script.

interesting again, running it right from bash, it works just fine, as
long as the first line calls v3.1.

Could geany be calling the 2.6 interpreter, even with v3 in the first
line?  oh my, that is unexpected, just tried it.

#!/usr/bin/python3
import sys
print(sys.version)

from geany yields:
2.6.4 (r264:75706, Dec  7 2009, 18:43:55) 
[GCC 4.4.1]

but from bash yields:
3.1.1+ (r311:74480, Nov  2 2009, 15:45:00) 
[GCC 4.4.1]
