在pandas中根据时间间隔删除行

import pandas as pd

# 创建一个示例DataFrame
data = {'date': ['2022-01-01', '2022-01-02', '2022-01-03', '2022-01-04', '2022-01-05'],
        'value': [10, 20, 30, 40, 50]}
df = pd.DataFrame(data)

# 将日期列转换为日期类型
df['date'] = pd.to_datetime(df['date'])

# 设置时间间隔
time_interval = pd.Timedelta(days=2)

# 根据时间间隔删除行
df = df.drop(df[df['date'] < df['date'].max() - time_interval].index)

print(df)

        date  value
3 2022-01-04     40
4 2022-01-05     50
