详解pandas删除缺失数据(pd.dropna()方法)
pandas中的dropna函数是用于过滤和删去缺失数据的列或行的常用函数。具体使用方法是通过调用该函数并传入所需要操作的数据对象,可以是Series或DataFrame,然后返回一个仅含非空数值和索引的新对象。对于Series,可以使用data[column_name].dropna()来删除指定列中的缺失值。例如,对于Series data['update_level'],可以使用data['update_level'].dropna()来删除该列中的缺失值。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
