Pandas 相當於密集秩

Question

我正在嘗試在 pandas 中復制密集等級 SQL 語句。 SQL 語句如下所示：

            ,DENSE_RANK() OVER(PARTITION BY [Team],[Season] ORDER BY [Team], 
       [Season],CAST([characteristic].[value] AS INT) DESC)  AS ROW#

到目前為止，我嘗試過的 python 代碼只排在一列上，而不是兩列。

    df['Rank'] = df1.Team.rank(method='dense').astype(int)

有沒有人有更好的解決方案？

Answer 1

IIUC 用途：

df[['Rank1', 'Rank2']] = df1[['Team','Season']].rank(method='dense').astype(int)
