pandas的split函数

pandas的split函数是DataFrame和Series对象的一个方法，用于将字符串按照指定的分隔符进行分割。它的语法是：str.split(pat=None, n=-1, expand=False)。其中，pat是字符串分隔符，默认为空格；n用于指定需要分割的次数，默认为-1，表示返回所有分割的字符串；expand则是用于控制是否将拆分的字符串展开为单独的列，默认为False，如果设置为True，则会将分割后的字符串展开为多列的DataFrame。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
