random.randrange(1, 10)#【1, 10】随机返回一个整数,会出现前,不会出现后面的数据,相当于range(), 不顾后端。 random.uniform(1, 10)# 【1,10】 返回随机一个小数,不含两端 random.choice(item)# 单例集合随机选择1个 random.sample(item, n)# 单例集合随机选择n个 random.shuffle(item)# 洗牌单列...
我们可以使用print语句将其输出到控制台: print("Randomly picked fruit:",random_fruit) 1. 至此,我们已经完成了整个"Python List Random Pick"的实现。下面是完整的代码示例: importrandom fruits=['apple','banana','orange','kiwi','watermelon']random_fruit=random.choice(fruits)print("Randomly picked fru...
Modulerandomin the standard Python library offers a wealth of possibilities for generating and using pseudo-random numbers, but it does not offer this specific functionality, so we must code it as a function of our own: import random def random_pick(some_list, probabilities): x = random.unifo...
The following example shows the usage of the Python random.choice() method.Open Compiler import random #imports the random module # Create a list, string and a tuple lst = [1, 2, 3, 4, 5] string = "Tutorialspoint" tupl = (0, 9, 8, 7, 6) dct = {1: 'a', 2: 'b', 3: ...
>>> import random >>> random.choice ( ['apple', 'pear', 'peach', 'orange', 'lemon'] ) 'lemon' 洗牌: >>> import random >>> items = [1, 2, 3, 4, 5, 6] >>> random.shuffle(items) >>> items [3, 2, 5, 6, 4, 1]...
Let’s think about a simple example where we have a set of numbers contained in a list,and we would like to pick one of those numbers uniformly at random. 在本例中,我们需要使用的函数是random.choice,在括号内,我们需要一个列表。 The function we need to use in this case is random.choice...
enemy = random.choice(["Troll", "Pirate", "Gorgon", "Monster"]) return weapons, enemy def play_game(): weapons, enemy = load_game() intro(enemy) choice(weapon, enemy) 然后需要更新现有函数以获取以下变量: def intro(enemy): ...def choice(weapon, enemy): ...etc. 注意items当前也具有...
defspam():"""This is a multiline comment to help explain what thespam()functiondoes."""print('Hello!') 索引和切片字符串 字符串和列表一样使用索引和切片。您可以将字符串'Hello, world!'视为一个列表,并将字符串中的每个字符视为一个具有相应索引的项。

Use random.choice() function to randomly select an item from a list, String, Dictionary, and set. Pick a single random number from a range
