选择两个给定日期之间的pandas dataframe，其中两列的值相等

import pandas as pd

# 创建示例dataframe
data = {'日期': ['2022-01-01', '2022-01-02', '2022-01-03', '2022-01-04', '2022-01-05'],
        '列1': [1, 2, 3, 4, 5],
        '列2': [1, 2, 3, 4, 5]}
df = pd.DataFrame(data)
df['日期'] = pd.to_datetime(df['日期'])  # 将日期列转换为日期类型

# 给定两个日期
start_date = '2022-01-02'
end_date = '2022-01-04'

# 筛选两个日期之间的数据，并且两列的值相等
filtered_df = df[(df['日期'] >= start_date) & (df['日期'] <= end_date) & (df['列1'] == df['列2'])]
