I stumbled upon Ted Dziuba’s blog today and found this gem: “Independent object cycles where one of the objects has a __del__ method don’t get garbage collected.” I didn’t know that.
I didn’t know Gunnery Sergeant Hartman knew Python either… Live and learn 🙂
This is how I learned to write decorators:
class Decorator:
def __init__(self, func):
self.func = func
def __call__(self, *args):
# do stuff
return self.func(*args)
But today I was reminded of the classic way of writing decorators:
def mydecorator(func):
def mydecorator_guts(*args, **kwargs):
# do stuff
return func(*args, **kwargs)
return mydecorator_guts
Simpler and more to the point. And NO CLASSES. This ain’t Java 🙂
I have a “for item in collection:” loop, as classic as it could be. The collection is sorted, there are duplicates. I need to return the last item if duplicate values exist.
It took me 15 minutes to arrive at for item in reversed(collection): solution. That is some slow thinking! Just when I needed to think fast. Sigh.
