Implement the integral part logn base 2 with bit manipulations

1.函数名可以被赋值 比如: def aaa(): pass b = aaa//将函数名字赋值给b b()//跟aaa()效果一样 2.return 2.1.如果函数不写return的话,会默认返回None 2.2.return后,函数下面的语句不会被执行,中断函数操作 2.3.return个什么东西都行,哪怕是个列表..... 3.pycharm使用断点调试的话,需要用debug模式(向右小箭头的小虫子) 4.参数: 默认参数必须写在后边 def aaa(a1, a2 = 1): pass//

2. Built-in Functions https://docs.python.org/3.4/library/functions.html?highlight=file The Python interpreter has a number of functions and types built into it that are always available. They are listed here in alphabetical order.     Built-in Funct

CIL: Common Intermediate Language 公共中间语言CLR: Common Language Runtime 公共语言运行库Creation of New Types is the essence(核心)of OOP. Type(类型) is defined by class and object(对象) is the instance(实例) of class. 赋值语句: 值域大的变量 = 值域小的变量:占位符foreach循环Three pillars(3大支柱

include /etc/openldap/openldap/schema/core.schema此 句是用来将目录所用到的schema文件包含进来:openldap一般默认带有几个schema,在我们的配置文件安装目录下的schema目录中存 放.本句中的core.schema是LDAP V3中必须的,它给出了LDAP V3中最基本的attribute和objects的定义.其它的还有:corba.schema.dyngroup.schema. java.schema nis.schema.o

英文文档: super([type[, object-or-type]]) Return a proxy object that delegates method calls to a parent or sibling class of type. This is useful for accessing inherited methods that have been overridden in a class. The search order is same as that used b
