范围是不可变的整数序列,通常用于for循环。 Ranges are immutable sequences of integers,and they are commonly used in for loops. 要创建一个范围对象,我们键入“range”,然后输入范围的停止值。 To create a rang...
And then when I run the random choice, Python returns one of these numbers back to me. 如果我重复同一行,我会得到一个不同的答案,因为Python只是随机选取其中一个对象。 If I repeat the same line, I’m going to get a different answer,because, again, Python is just picking one of those obj...
最后,我们在数据的直方图上绘制我们的预期分布: x_range = np.linspace(-5,15) y = normal_dist_curve(x_range) ax.plot(x_range, y,"k--") 结果显示在图 4.2中。我们可以看到这里,我们抽样数据的分布与正态分布曲线的预期分布非常接近: 图4.2:从均值为 5,比例为 3 的正态分布中绘制的数据的直方图,...
