按周间隔创建时间序列pandas数据帧的多个子集

import pandas as pd
import numpy as np

dates = pd.date_range(start='2022-01-01', end='2022-12-31', freq='D')
df = pd.DataFrame({'date': dates, 'value': np.random.randn(len(dates))})

df.set_index('date', inplace=True)

weekly_subsets = [group[1] for group in df.resample('W')]
