Write a Python program to select an item randomly from a list. Use random.choice() to get a random element from a given list. Example - 1 : Example - 2 : Example - 3 : Sample Solution-1: Python Code: # Import the 'random' module, which provides functions for generating random value...
Import therandom module:This module implements pseudo-random number generators for various distributions. Seedocumentation. The random module in Python offers a handychoice()function that simplifies the process of randomly selecting an item from a list. By importing the random module, you can directly...
The random library is a built-in Python library, i.e, you do not have to install it. You can directly import it. We will look at 3 different ways to select a random item from a list using the random library. 1. Random Index¶ importrandomnum_items=len(twitter_user_names)random_in...
(6) random.choice()从列表中随机返回一个元素。 # 随机获取一个元素import randoms = random.choice(["124dds", "ew6210", "98rac1"])print(s) 1. 输出结果(随机生成,结果会不一样) 124dds 1. (7) random.shuffle()对list列表随机打乱顺序,也就是洗牌。 # 洗牌import randomitem = [1, 2, 6,...

choice(pets) 'Cat' >>> random.choice(pets) 'Cat' 你可以把random.choice(someList)看成是someList[random.randint(0, len(someList) – 1]的一个简称。 random.shuffle()函数将对列表中的项目进行重新排序。这个函数原地修改列表,而不是返回一个新的列表。在交互式 Shell 中输入以下内容: 代码语言:...
