Python random() 函数Python 数字描述random() 方法返回随机生成的一个实数,它在[0,1)范围内。语法以下是 random() 方法的语法:import random random.random()注意:random()是不能直接访问的,需要导入 random 模块,然后通过 random 静态对象调用该方法。

python random 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。
1. 2. 3. random.choice 从序列中获取一个随机元素。其函数原型为:random.choice(sequence)。参数 sequence 表示一个有序类型, 它在 python 中不是一种特定的类型,而是泛指一系列的类型。列表、元组、字符串都属于 sequence。下面是使用 choice 的一些例子: ...
print(random.randrange(0,50,2)) # 14 # 随机取值string print(random.choice("python")) # n # 随机取值list lst = ["one", "two", "three"] print(random.choice(lst)) # one # 随机取值tuple tp = ("one", "two", "three")
random.randint(1,100)随机数中是包括1和100的。python中对random.randint() 的源码解释如下 def randint(self, a, b):"Return random integer in range [a, b], including both end points."翻译过来就是返回值是在 [a, b] 区间的随机数(integer类型),其中包括 a和 b。

When you run the above code,.uniform() will generate a single random floating-point number in the range [0, 1). In other words, the lowest number will be 0, while the largest number will be just less than 1. Should you want a number from 0 to just before 10, for example, you’...
