Pandas中的reset_index()方法用于重置DataFrame的索引。在默认情况下,reset_index()方法会移除MultiIndex的所有级别,即将索引重置为从0开始的默认数字。如果我们需要将原始DataFrame重新分配给对其应用reset_index()方法的结果,可以直接重新分配它(df = df.reset_index())或将参数inplace=True传递给该方法(df.reset_index(inplace=True))。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
