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。
如果除数为0,会产生ZeroDivisionError。 取余运算符(modulo,%) %运算符求两个数相除的余数,也叫模。例如4%3等于1,4.0%3.0等于1.0。如果除数为0,会产生ZeroDivisionError。 乘方运算符(power,**) **运算符用来计算乘方。a ** b得到a的b次方。例如,2 ** 7等于128,4 ** -2等于0.0625。 在除了/以外的运算...
You can use the modulo operator to create cyclic iteration. Take a look at an example using the turtle library to draw a shape: Python import turtle import random def draw_with_cyclic_iteration(): colors = ["green", "cyan", "orange", "purple", "red", "yellow", "white"] turtle....

In this condition, the modulo operator returns the remainder of dividing number by 2, and the equality operator compares the result with 0, returning True or False as the comparison’s result. Then you use the all() function to determine if all the conditions are true. In this example, ...
we must follow the rules of operator precedence. 2 or more operators in a precedence represent a group. The parenthesis has the highest precedence, followed by the exponentiation. then the unary plus, unary minus group, then the multiplication, division, floor division, modulo group, then the ...
除此之外,还有一些其他工具,比如mimetools、unittest等,上述四个tools作用于内建类型和函数、类等,比较通用,也较为常用。 -operator : 内置的操作符模块 -collections : 简化容器类型的一些操作和使用 -itertools : 可迭代类型工具 -functool...
