sort can take in a comparison function.
The comparison function takes in 2 arguments and returns them in sorted form.

Eg.
def copare(e1,e2):
return e1-e2

Eg. this will return a negative number to indicate it is to be reversed to sort it
So to sort the array called 'items', you would use
The only diff in ur code is that they used a 'lambda function' which is a function but without a name.) My compare function has the name 'compare' associated to the funtion object.
I pass the function into the sort function as an argument. In their code, they create an anonymous function there and then to pass in as an argument. So their code could be re-written as:
Quote:
def mycompare(a,b):
cmp(a.Title(), b.Title())
items.sort( mycompare )
