Python's equivalent for Ruby's define_method?

Question

Is there a Python equivalent for Ruby\'s define_method, which would allow dynamic generation of class methods? (as can be seen in Wikipedia\'s Ruby example code

Answer 1

In Python, you can just set a method on a class:

>>> class Spam:
...     def __init__(self, x):
...         self.value = x
...
>>> Spam.getvalue = lambda self: self.value
>>> ham = Spam('ham')
>>> ham.getvalue()
'ham'

Fancier stuff is possible with decorators.
