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。
print("First random number of length 3 is:", number1) number2 = random.randrange(100,1000) print("Second random number of length 3 is:", number2) 输出: First random number of length 3 is:813 Second random number of length 3 is:770 示例4:生成随机负整数: 让我们看一个生成 -50 到 ...

from random import randint:从random模块中导入randint函数,该函数用于生成一个指定范围内的随机整数。 初始化变量: a = list():初始化一个空列表a,用于存储随机生成的整数。 n = 0:初始化变量n,用于记录列表a中元素的个数。 设置范围和个数: lower_bound = 1:设置随机数的下限为1。 upper_bound = 10...
luckynumber = random.randint(1,10) print ("Your lucky number is {}".format(luckynumber)) Choose a random item from a list from the following: cheese_types = ['brie', 'cheddar', 'feta'] random.choice cheese = random.choice(cheese_types) ...
random.seed(a=None, version=2) seed函数用于初始化Python中的伪随机数生成器。random模块使用种子值作为基础来生成随机数。如果不存在种子值,则需要系统当前时间。如果在调用任何random模块函数之前使用相同的种子值,则每次都会获得相同的输出。 importrandom# Random number with seed 6random.seed(6)print(random....
The syntax of this function is: random.randint(a,b) This returns a number N in the inclusive range [a,b], meaning a <= N <= b, where the endpoints are included in the range. Also Read: Python Program to Randomly Select an Element From the List ...
