Let’s look at a couple of common sequence operations on strings. 让我先定义一个字符串。 Let me first define a string. 让我们来看看“Python” Let’s just go with "Python." 同样,如果我想知道我的字符串有多长,我可以使用len函数。 Again, if I wanted to find out how long is my string,...
它们应该只在极端情况下使用:例如,当使用一个包的私有API 的重要部分时。 最后,给find_packages一个白名单,列出要包含的内容,以避免虚假文件,这是一个好主意。例如, setuptools.find_packages(include=["my_package∗"]) 一旦我们有了setup.py和一些 Python 代码,我们想把它做成一个发行版。一个发行版可以有...

实现find_closest函数,输入一个坐标location和centroid集合(类簇坐标),返回距离location最近的centroid。 需要使用utils.py中的distance函数来计算两个location的距离,如果两个centroid等距离,返回序号较小的那个。 # distance函数defdistance(pos1,pos2):"""Returns the Euclidean distance between pos1 and pos2, which...
