pandas 字符串函数

Pandas提供了一系列的字符串函数，用于对DataFrame中的字符串数据进行操作。这些函数以"str"开头，并可用于对Series和DataFrame中的字符串列进行处理。一些常用的Pandas字符串函数包括：lower()将字符串转换为小写、upper()将字符串转换为大写、len()返回字符串的长度、strip()去除字符串两侧的空白字符、contains()判断字符串是否包含某个子串、replace()替换字符串中的某个子串、split()将字符串拆分成多个子串并返回一个列表等。这些函数的使用可以大大提高处理字符串数据的效率。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
