unique、nunique,也是仅适用于series对象,统计唯一值信息,前者返回唯一值结果列表,后者返回唯一值个数(number of unique) sort_index、sort_values,既适用于series也适用于dataframe,sort_index是对标签列执行排序,如果是dataframe可通过axis参数设置是对行标签还是列标签执行排序;sort_values是按值排序,如果是dataframe对...

# Return missing valuesairquality.isna()我们还可以将isna方法与sum方法链接起来,该方法将返回数据框架中每列缺失值的细分。# Get summary of missingnessairquality.isna().sum()我们注意到CO2列是唯一缺少值的列。利用可视化发现缺失数据的...
Ceremony最小值为1,最大值为88,对应Year中共取得88个Unique,代表本数据集或许正确包含了88届奥斯卡的数据。奖项Award共有114个不同的值,有待进一步考证。Winner的最小值最大值均为一,结合该列存在大量的缺失值这一事实,可以判断Winner一列中,未获奖的提名者直接标记为空值。Name和Film的Unique为总数量的60%左右...
