在循环内创建多个OR条件，以便在带有datetime.time的.loc中使用

import pandas as pd
import datetime

# 创建包含时间数据的DataFrame
df = pd.DataFrame({'time': [datetime.time(8, 30), datetime.time(9, 0), datetime.time(9, 30), datetime.time(10, 0)],
                   'value': [1, 2, 3, 4]})

# 创建OR条件
conditions = []
for i in range(2):
    start_time = datetime.time(8 + i, 30)
    end_time = datetime.time(9 + i, 0)
    conditions.append((df['time'] >= start_time) & (df['time'] <= end_time))

# 将OR条件组合在一起
combined_condition = conditions[0]
for i in range(1, len(conditions)):
    combined_condition = combined_condition | conditions[i]

# 使用.loc选择符合条件的行
result = df.loc[combined_condition]

print(result)

       time  value
0  08:30:00      1
1  09:00:00      2
