Python GroupBy时间间隔

import pandas as pd

# 创建一个示例数据集
data = {'timestamp': ['2022-01-01 10:00:00', '2022-01-01 10:05:00', '2022-01-01 10:10:00', '2022-01-01 10:15:00'],
        'value': [1, 2, 3, 4]}
df = pd.DataFrame(data)

# 将时间列转换为Datetime类型
df['timestamp'] = pd.to_datetime(df['timestamp'])

# 设置时间列为索引
df.set_index('timestamp', inplace=True)

# 按照5分钟间隔进行分组，并计算每组的和
result = df.resample('5T').sum()

print(result)
