在第二个示例中,Python 首先计算相等运算符 ( ==) 并引发 a ,SyntaxError因为无法比较Falseand not。您可以not True用括号 ( ())将表达式括起来以解决此问题。这个快速更新告诉 Python 首先计算括号中的表达式。 在逻辑运算符中,not比具有相同优先级的and运算符和运算符具有更高的优先or级。
random 模块位于Python标准库中 因此首先导入import random 部分函数功能介绍 一random.random() 生成0<=n<1随机浮点数 二random.unifrom(a,b) 生成指定范围内的浮点数,包含a,b 三random.randint(a,b) 生成指定范围整数,包含a,b.其中a为下限,b为上限。

值由random_int函数生成,该函数生成给定范围内的数字(包括)。 <?php$arr = array();for ($i = 0; $i < 20; $i++) { array_push($arr, random_int(1, 10));} 随机性的来源非常好(取决于系统)。 如果要将此随机数数组生成器作为函数,请执行以下操作: <?phpfunction random_ints($count, $min...
