If you have an existing class, you can bind new methods to it by simply using setattr(). >>> class A: ... pass ... >>> setattr(A, 'x',lambda self: 'foo') >>> a=A() >>> a.x() 'foo' >>> class B(A): ... pass ... >>> b=B() >>> b.x() 'foo' You can also use new.classobj() to create arbitrary classes on-the-fly. See the documentation for the new module, and google "python metaclasses" Cheers _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
