random.random()无需传参数，该函数返回一个[0,1)的浮点数，如果想获取其他区间的，请自行设计一个函数映射，例如想获取[-1, 1)之间，那么设计为：f(x) = 2x - 1 写成代码就是：x = random.random()x = 2 * x - 1

(2,2), (2,1)] 现在,如果我们想要计算多边形周长的距离,我们需要计算每个点之间的距离。为此,我们需要一个函数来计算两点之间的距离。以下是两个这样的函数: importmathdefdistance(p1, p2):returnmath.sqrt((p1[0]-p2[0])**2+ (p1[1]-p2[1])**2)defperimeter(polygon): ...
import random, stringwith StringJoiner() as joiner:for i in range(15):joiner.append(random.choice(string.ascii_letters))print(joiner.result) 这段代码构造了一个包含 15 个随机字符的字符串。它使用从list继承的append方法将这些字符附加到StringJoiner上。当with语句超出范围(回到外部缩进级别)时,将调用__...
