1. 取模运算符（Modulo Operator） 取模运算符是 Python 中的一种数学运算符，用于求余数。其基本语法为：```python result = a % b ```工作原理：`a` 是被除数，`b` 是除数，`%` 返回 `a` 除以 `b` 后的余数。 常见用途：用于判断一个数是否是另一个数的倍数、实现循环逻辑或处理周期性问题。
Similarly you can use modulo, floor division, exponentiation the same way. Any arithmetic operator in front of the equal sign is called a compound operator.It's a more elegant way of coding your expressions, so you should use it. 等号前的任何算术运算符都称为复合运算符。这是一种更优雅的...
In the first two examples, you use the addition and division operators to construct two arithmetic expressions whose operands are integer numbers. In the last example, you use the equality operator to create a comparison expression. In all cases, you get a specific value after executing the ...
其次,调用字典的get()获取相应的表达式。 fromfutureimport division x = 1 y = 2 operator = "/" result = { "+" : x + y, "-" : x - y, "*" : x * y, "/" : x / y } print result.get(operator) 输出为0.5; 另一种使用switch分支语句的方案是创建一个switch类,处理程序的流程。
5.0 / 2 returns the floating-point number 2.5, and int(2.5) returns the integer 2 with the .5 removed.Integer DivisionIf writing int(5.0 / 2) seems a little long winded to you, Python provides a second division operator called the integer division operator (//), also known as the ...
向下取整运算法(floor division) 运算符(operator) 将第一个数字除以第二个数字,然后将结果向下取整到最接近的小的整数。当其中一个数字为负数时,这将变得有趣。例如: >>> -3//2 -2 1. 2. 最终结果是小于除法运算结果的整数(除法运算结果是 -3/2=-1.5, 所以最终结果是 -2)。
Enter an integer number: 8 Square of 8 is 64 2)通过使用指数运算符(**):(数字** 2) (2) By using Exponent Operator (**): (number**2)) The another way is to find the square of a given number is to use Exponent Operator (**), it returns the exponential power. This operator is...

1989年底罗萨姆始创了python。他期望有一种工具可以完成日常系统管理任务,并能够访问Amoeba分布式操作系统的系统调用。罗萨姆为此创造出了一种通用的程序设计语言。1991年,python发布了第一个公开发行版。 3. python特点 3.1 高级 语言的升级:汇编语言→C→C++\Java等现代编译语言→可以进行系统调用的解释性脚本语言,pe...
