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:...

1.1.5: Random Choice 随机选择 通常,当我们使用数字时,偶尔也会使用其他类型的对象,我们希望使用某种类型的随机性。 Often when we’re using numbers, but also,occasionally, with other types of objects,we would like to do some type of randomness. 例如,我们可能想要实现一个简单的随机抽样过程。 For ...
我们还可以利用random模块提供的sample和choice函数来简化上面的代码,前者可以实现对列表元素的无放回随机抽样,后者可以实现从列表中随机抽取一个元素,修改后的代码如下所示。 """ 双色球随机选号程序 Author: 骆昊 Version: 1.1 """ import random red_balls = [i for i in range(1, 34)] blue_balls = ...
Use therandom.choice()method: Thechoice()function takes one argument: the no-empty sequence like a list, tuple, string, or any iterable like range.Pass your list as an argument, and It will return a random element from it. Note: Thechoice()function returns a random element from the non...
此时输入li[2],程序会报错,提示index out of range... 可是如果此时输入的是li[1:99],会显示“武藤兰”,尽管我们切片切到月球去了,可是程序会“有多少给多少”,因此在切片的时候,程序会显得比较“宽容”。 *Part6: 验证码小程序 1defcheck_code():2importrandom3checkcode =''4foriinrange(4):5current...

The math module contains more advanced numeric tools as functions, while the random module performs random number generation and random selections (here, from a Python list, introduced later in this chapter): >>> import random >>> random.random( ) 0.59268735266273953 >>> random.choice([1, 2,...
