Hello,
I am using things like:

The old syntax for exceptions still works in Python2.x (all versions).
The new syntax works in Python2.6+ and Python3.
try:
whatever
except Exception,msg: # Old syntax
print msg
with open("myfile.txt") as f:
for line in f:
print line
You don't need the new fangled with statement if you want to be
compatible with older versions of Python2. (It's nice and convenient,
but not necessary.)
f = open("myfile.txt")
for line in f:
print line
f.close() # This is what the "with" statement guarantees; so now just
do it yourself

Things that seems to be new in python 2.6 and higher, however reading
http://docs.python.org/tutorial/errors.html and this not clear when
this new syntaxes appeared.
My trouble is that I want to make something similar above compatible
with python 2.5, but when running python2.5 I got:
except Exception as msg:
^
SyntaxError: invalid syntax
If there's a way (e.g. from __future__ ..., inherited modified
Exception class, etc) that could give a solution to keep my code in
python 2.6 syntax as above but compatible with python 2.5, that would
be appreciated.
Many thanks in advance,
Alan
