Let’s see how we can use the random choice function to carry out perhaps the simplest random process – the flip of a single coin. 让我们看看如何使用随机选择函数来执行可能是最简单的随机过程——抛一枚硬币。 I’m first going to import the random library. 我首先要导入随机库。 So I type ...
def getRandomWord(wordList): # This function returns a random string from the passed list of strings. wordIndex = random.randint(0, len(wordList) - 1) return wordList[wordIndex] 在第42 行,我们通过调用randint()并传入两个参数,将这个列表的随机索引存储在wordIndex变量中。第一个参数是0(表示...
For example, a Boolean value like True or False is read-only, but you’ll find both mutable and immutable sequences in Python:A Python list represents a mutable sequence of arbitrary elements. A Python string is an immutable sequence of characters....
