在Python中检查2年内Dataframe的条件

import pandas as pd
from datetime import datetime, timedelta

data = {'日期': ['2020-01-01', '2020-02-15', '2021-03-10', '2022-04-20'],
        '数值': [10, 20, 30, 40]}
df = pd.DataFrame(data)

df['日期'] = pd.to_datetime(df['日期'])

current_date = datetime.now()

two_years_ago = current_date - timedelta(days=365*2)

filtered_df = df[df['日期'] >= two_years_ago]
