python3教程:Operator模块 Operator——标准功能性操作符接口. 代码中使用迭代器时,有时必须要为一个简单表达式创建函数。有些情况这些函数可以用一个lambda函数实现,但是对于某些操作,根本没必要去写一个新的函数。因此operator模块定义了一些函数,这些函数对应于算术、比较和其他与标准对象API对应的操作。
算数运算符 + - * / ** % /表示自然除,结果是浮点数。//为整除。python2.x版本/和//都是整除。 用法举例 In [4]: 1+1 Out[4]: 2 In [5]: 2*2 Out[5]: 4 # 自然除 In [8]: 10 / 3 Out[8]: 3.3333333333
