如何按月份和另一列pandas数据框分组

import pandas as pd

data = {'日期': ['2022-01-01', '2022-01-02', '2022-02-01', '2022-02-02', '2022-03-01', '2022-03-02'],
        '数值': [1, 2, 3, 4, 5, 6],
        '其他列': ['A', 'B', 'C', 'D', 'E', 'F']}
df = pd.DataFrame(data)

df['日期'] = pd.to_datetime(df['日期'])

df['月份'] = df['日期'].dt.month

grouped = df.groupby(['月份', '其他列'])

average = grouped.mean()

sorted_df = df.sort_values(['月份', '其他列'])
