prod() will be easier to use when you already have the factors stored in an iterable. Another new function is math.isqrt(). You can use isqrt() to find the integer part of square roots: Python >>> import math >
In my experience, these are two of the lesser used itertools functions, but I urge you to read their docs an experiment with your own use cases! Here are a few places where you can find more examples of itertools in action (thanks to Brad Solomon for these fine suggestions): What is ...

In a perfect world, data would be neatly tucked away inside HTML elements with clear labels. But the web is rarely perfect. Sometimes, we'll find mountains of text crammed into basicelements. To extract specific data (like a price, date, or name) from this messy landscape, we'll need t...

复制 X = [x.flatten() for x in X] return X 现在,我们终于准备好在预处理的数据集上训练分类器了。 支持向量机 支持向量机(SVM)是一种用于二分类(和回归)的学习器,它试图通过决策边界将两个不同类标签中的示例分离开来,以使两个类之间的余量最大化。 让我们回到正负数据样本的示例,每个样本都具有两个...
We use an automated processes to find bugs. In the issue trackers for other decompilers, you will find a number of bugs we've found along the way. Very few to none of them are fixed in the other decompilers. The code in the git repository can be run from Python 2.4 to the latest...
