Amazing Python 3: "@"
1. This an interesting usage that I don't know how to call it. See example:def hehe(tt): return 'hehe'+tt()@hehedef test(): return 'test'print test
The output is same as:
def hehe(tt): return 'hehe'+tt()def test(): return 'test'test = hehe(test)print test
Output:
hehetest
P.S: It enables such an easy way to invoke functions by strings! - cloud

2. Use "@staticmethod" to realize static method in Python (Python does not have keyword "static"):
class AClass(): @staticmethod def astatic(): # pay attention that there's no "self" here! print 'It's a static method!'AClass.astatic()
Output:
It's a static method!
By the way, there's another way to make a method static with a same output:
class AClass(): def aclassmethod(): print 'It's a static method!' aclassmethod = classmethod(aclassmethod) # you can write "whatevername = classmethod(aclassmethod)" after Python2.5
