我一直这样:
class Event(list):
"""Event subscription.
A list of callable objects. Calling an instance of this will cause a
call to each item in the list in ascending order by index.
Example Usage:
>>> def f(x):
... print 'f(%s)' % x
>>> def g(x):
... print 'g(%s)' % x
>>> e = Event()
>>> e()
>>> e.append(f)
>>> e(123)
f(123)
>>> e.remove(f)
>>> e()
>>> e += (f, g)
>>> e(10)
f(10)
g(10)
>>> del e[0]
>>> e(2)
g(2)
"""
def __call__(self, *args, **kwargs):
for f in self:
f(*args, **kwargs)
def __repr__(self):
return "Event(%s)" % list.__repr__(self)
但是,就像我看到的所有其他内容一样,没有为此自动生成的pydoc,也没有签名,这确实很糟糕。
