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。 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。接下来看看下面这个简单的例子: ...

The search methods look for a single, hard-coded substring, and they are always case-sensitive. To do case-insensitive searches of a strings, you must calls.lower()ors.upper()and make sure your search strings are the appropriate case to match. Thereplaceandsplitmethods have the same limitati...
