how to repeat function definitions less

[andrew cooke]

is this what you want (python 3.0)?

>>> class Colours:
...   def __init__(self):
...     for colour in ['red', 'blue']:
...       setattr(self, colour, lambda value, c=colour: self.write(value, c))
...   def write(self, value, colour):
...     print(value, colour)
...
>>> c = Colours()
>>> c.red(1)
1 red
