在循环中删除pandas数据帧中的时间间隔

import pandas as pd

df = pd.DataFrame({'时间间隔': ['2022-01-01', '2022-01-02', '2022-01-03', '2022-01-04']})

df['时间间隔'] = pd.to_datetime(df['时间间隔'])

result = pd.DataFrame(columns=['时间间隔'])

for index, row in df.iterrows():
    if row['时间间隔'] != pd.Timestamp('2022-01-02'):
        result = result.append(row)

print(result)
