函数中的局部变量最快，类级别属性（如 self.name）慢一些，全局导入函数（如 time.time）最慢。 你可以通过这种看似没有必要的代码组织方式来提高效率： # Example #1 class FastClass: def do_stuff(self): temp = self.value # this speeds up lookup in loop for i in range(10000): ... # Do some...

Unlike functions, classmethods will create a method also when accessed as class attributes (in which case they bind the class, not to the type of it). So SomeClass.classm is SomeClass.classm is falsy.>>> SomeClass.classm <bound method SomeClass.classm of <class '__main__.SomeClass...
