写一段python代码,要求在导入一个xlsx文件,可以将其中的数据在四个时间段(6:00:00~7:30:00,7:30:00~15:30:00,15:00:00~17:00:00,17:00:00~6:00:00)区分,统计四个方向(东南西北)的区别下所出现的次数,

```python
import pandas as pd
from datetime import datetime, timedelta
def count_directions(file_path):
# 读取xlsx文件
data = pd.read_excel(file_path)
# 定义时间段和方向
time_periods = [
('6:00:00', '7:30:00'),
('7:30:00', '15:30:00'),
('15:00:00', '17:00:00'),
('17:00:00', '23:59:59'),
('00:00:00', '6:00:00')
]
directions = ['东', '南', '西', '北']
# 初始化计数器
counts = {d: [0] * len(time_periods) for d in directions}
# 遍历数据,统计每个时间段和方向的次数
for index, row in data.iterrows():
time_str = row['时间']
direction = row['方向']
time_obj = datetime.strptime(time_str, '%H:%M:%S')
for i, (start, end) in enumerate(time_periods):
start_obj = datetime.strptime(start, '%H:%M:%S')
end_obj = datetime.strptime(end, '%H:%M:%S')
if start_obj <= time_obj < end_obj:
counts[direction][i] += 1
break
return counts
file_path = 'your_file_path.xlsx'
result = count_directions(file_path)
print(result)
