您可以使用random.choice为length次选择一个随机字符。以下是一些可能的答案:对于for循环: import randomchars = input("Characters: ")length = int(input("Length: "))result = ''for _ in range(length): result += random.choice(chars) 或与列表comps: import randomchars = input("Characters: ")lengt...

We will be using that to simulate simple random processes,but we’ll also take a look at some other tools the Python has to generate random numbers. 我们将使用它来模拟简单的随机过程,但我们还将看看Python生成随机数的其他一些工具。 Let’s see how we can use the random choice function to car...
现在,作为面向对象的程序员,我们清楚地认识到polygon类可以封装点的列表(数据)和perimeter函数(行为)。此外,point类,就像我们在第十六章中定义的那样,Python 中的对象,可能封装x和y坐标以及distance方法。问题是:这样做有价值吗? 对于以前的代码,也许是,也许不是。有了我们最近在面向对象原则方面的经验,我们可以以创...
