本文将全面解析operator模块的各个函数,通过具体案例深入理解它们的用途和优势。 一、operator模块概览 operator模块包含了对应于Python所有内置运算符的函数,这些函数可以直接在代码中调用,用于替代传统的运算符语法。这在某些场景下,尤其是需要将运算符作为参数传递给其他函数的情况下,显得尤为有用。 二、数学运算符函数 ...

在Python语言中，运算符`<<`表示左移位运算符（Bitwise Left Shift Operator）。它将一个数的二进制表示向左移动指定的位数。具体而言，`x << y`表示将`x`的二进制表示向左移动`y`位。左移操作会在低位补0，相当于将原来的数乘以2的`y`次方。例如，假设`x`的二进制表示为`1101`（十进制为13...
