python 一切事物都是对象，对象基于类创建
类：(列表)功能集合
查看对象相关成员：var,type,dir
int(x=0) -> int or long int(x, base=10) -> int or long
def bit_length(self): 返回表示该数字的时候占用的最少位数
int.bit_length(*)
eg:int.bit_length(27) ---> 5
说明:27用二进制表示：bin(27) --->'0b11011' (其中ob表示二进制，11011表示27)
def conjugate(self, *args, **kwargs): 返回该复数的共轭复数
