Pyrhon2.5 to 2.4 conversion

[tare...@gmail.com]

Hi,

I am currently using oauth2.py library, and it works fine on one of my
PC's (python2.5), but later on when I tried to use it with python2.4
the following line (line 332 in http://github.com/simplegeo/python-oauth2/blob/master/oauth2/__init__.py)
showed a syntax error

items = [(k, v if type(v) != ListType else sorted(v)) for k,v in
sorted(self.items()) if k != 'oauth_signature']

So it there a way to convert this line to a python2.4 compliant
syntax.

Thanks a lot,
Tarek

This part is your problem:

(k, v if type(v) != ListType else sorted(v))

Conditional expressions like that were added in v2.5:
http://docs.python.org/whatsnew/2.5.html#pep-308-conditional-expressions

Here's an untested substitute:

def sort_or_tuple(k, v):
if type(v) != ListType:
return k, v
else:
return sorted(v)

items = [sort_or_tuple(k,v) for k,v in sorted(self.items()) if k !=
'oauth_signature']

Of course, the more obvious solution is just to upgrade your Python;
it's well worth it!

Cheers,
Chris

You would be better off installing Python2.5 on the PC rather than trying
to backport the library to 2.4. There could be thousands of changes
needed to backport the library.

I think the clearest is:

items = []
for k, v in sorted(self.items()):
if k != 'oauth_signature':
if type(v) == ListType:
v = sorted(v)
items.append((k, v))
