installation in mac os x

[Karl Jansson]

Hi,

I was doing the tutorial at http://www.python.org/doc/current/ 
tutorial/, and I came across some code that did not work,  and I got  
the following error:  	AttributeError: 'str' object has no attribute  
'format'.

So I downloaded a .dmg of python 2.6.2 and then I installed it.  But  
it's not working.  Running the Python launcher, the "new" command in  
the file menu is grey, and won't work, so I can't make any scripts.

Does anyone know how to make python 2.6.2 work in mac os x?

Thanks,
Stefan
