Python与pandas计算数据的季度之间的小时

import pandas as pd
from datetime import datetime

data = {'datetime': ['2022-01-01 10:30:00', '2022-04-01 15:45:00', '2022-07-01 08:15:00', '2022-10-01 18:00:00']}
df = pd.DataFrame(data)
df['datetime'] = pd.to_datetime(df['datetime'])
df.set_index('datetime', inplace=True)

quarterly_hours = df.resample('Q').sum().dt.total_seconds() / 3600

print(quarterly_hours)
