Swapping 2 variable values in python

I have been using python a little recently to build some internal tools and am really really impressed. It is the nut crcker to the c# sledge hammer.

A community accepted web frame work seems to be the main thing lacking; many shops are rolling their own. I think this fragments the community and prevents python from competing effectivly with ruby/rails.

Django, which is the main player, seems to insist you use their orm which doesnt fit with our architecture or ideological commitments;)

Either way python has some geat features. For example one line variable swaping

a = 1
b = 2

a, b = b, a

You can swap the values of two variables without the use of a third variable and in one line.

In c# you can do this without the 3rd variable by using xor.

int a = 1;
int b = 2;

a ^= b;
b ^= a;
a ^= b;

Still three lines though; not nearly as elegant as the python solution.

This is a lovely little trick which gives a hint of how flexible and powerful python can be in more 'real' world uses.
