Sure, piece of cake:
>>> class test:
... def func1(self): print 'func1 called'
...
>>> class test2:
... def func1(self): print 'other func1'
...
>>> x = [test(), test2(), test()]
>>> def call_this_func(lst, func_name):
... for e in lst:
... getattr(e, func_name)()
...
>>> call_this_func(x, 'func1')
func1 called
other func1
func1 called
>>>
Note that the getattr raises an AttributeError if func_name doesn't
exist in the object; you should probably wrap it in a try/except.
