I also talked about the first method of data mining - regression - which allows you to predict a numerical value for a given set of input values.

我还谈到了第一种数据挖掘的方法—回归—使用它可以根据一组给定的输入值预测数字值。

The dictionary is a heterogeneous, mutable container that relies on a key-to-data value mapping, rather than a particular numerical order to access items from the container.

dictionary 是一种异构的、易变的容器，依赖键到数据值的映射（而不是特定的数字次序）来访问容器中的元素。

This simple function steps through the data (which is assumed to be a Python container holding numerical data), calculates the mean value of the set of data, then returns the value.

这个简单的函数遍历data(假设data为一个容纳有数字数据的python容器)，计算一组数据的平均值，然后返回值。
