Pandas按季节进行重采样

import pandas as pd
data=pd.read_excel('asl.xlsx')
data=data.set_index('time')
season_data=data.iloc[2:,:]
season_data.resample('3M',closed='left').mean().to_excel('seasonal.xlsx')
seasonal=season_data.resample('3M',closed='left').mean()
seasonal.iloc[::4,:].to_excel('autumn.xlsx')
seasonal.iloc[1::4,:].to_excel('winter.xlsx')
seasonal.iloc[2::4,:].to_excel('spring.xlsx')
seasonal.iloc[3::4,:].to_excel('summer.xlsx')
