Sorting a list of classes

[Ray&Maria]

No, you can sort classes, too.  It is very useful if you want to sort a list
of plug-ins in a pull-down menu.

class A:
    className = "A"
class B:
    className = "B"
class C:
    className = "C"

classList = [B, C, A]
print "before sorting:", classList
classList.sort(lambda a, b: cmp(a.className, b.className))
print "after sorting:", classList
