does anyone know a nice implementation of callbacks in python? i have
issues mixing named & unamed parameters. i want build a callback over
a function such that some parameters are passed when callback is
created and the rest are passed when the function is called.
example:
callback = Callback(function, x=1, y)
callback(z, t=4, u)
First problem is that all unnamed arguments must come BEFORE named ones (Python
limitation). To do what you want define you callback as a class instead.
class Callback(object):
def __init__(x, y):
self.x = x
self.y = y
def __call__(z, t, u):
#
# Do what you want done at every callback
#
callback = Callback(x, y)
callback(z, t, u)
