笔记:data.replace⽅法与data.str.replace不同,后者做的是字符串的元素级替换。我们会在后⾯学习Series的字符串⽅法。 4、重命名轴索引 跟Series中的值⼀样,轴标签也可以通过函数或映射进⾏转换,从⽽得到⼀个新的不同标签的对象。 轴还可以被就地修改,⽽⽆需新建⼀个数据结构。 接下来看看下...

In this tutorial, you'll learn how to remove or replace a string or substring. You'll go from the basic string method .replace() all the way up to a multi-layer regex pattern using the sub() function from Python's re module.
