Python 如何检查日期是否在周范围内？

因此，如果退出日期在一周范围内，我需要返回布尔值True或false，这样我就可以继续对给定退出日期的预订值求和

week_start      week_end

0 2019-05-01    2019-05-08

1 2019-05-08    2019-05-15

2 2019-05-15    2019-05-22

3 2019-05-22    2019-05-29

4 2019-05-29    2019-06-05

week_start    datetime64[ns]

week_end      datetime64[ns]

以下退出日期是否在上述给定的周范围内（如果是的话）以及总预订价值^^

Exit_date = [ '2019-05-19','2019-05-27', '2019-05-26', '2019-05-28', '2019-05-27','2019-05-27', '2019-05-22', '2019-05-18', '2019-05-25',  '2019-05-25',  '2019-05-17', ' 2019-05-25']

booking_cost = ['113.3250','68.3250', '62.4900','80.9917', '79.9900', '41.6600', '50.8250','41.6600', '50.8250','68.3200','68.3200','114.9920']

data ={'Exit_date': Exit_date, 'booking_cost': booking_cost}


Exit_df = pd.DataFrame(data, columns=['Exit_date','booking_cost' ]) # exit date date frame
Exit_df['Exit_date'] = pd.to_datetime(Exit_df['Exit_date'])

print(Exit_df.head())

因此，如果退出日期在一周范围内，我将要计算预订价值的总和。。。像这样的

Total_Sales =0
if daterange_df['week_start'] <= parking_master['Exit_Date'] <= daterange_df['week_end'] :
  Total_Sales=+Exit_df['Booking Cost']
print(Total_Sales)

总销售额=0
如果daterange_df['week_start']用于列表理解，对于计数
True
s-匹配
Exit_Date
值：

z = zip(daterange_df['week_start'], daterange_df['week_end'])
daterange_df['count'] = [parking_master['Exit_Date'].between(s, e).sum() for s, e in z]
print (daterange_df)
  week_start   week_end  count
0 2019-05-01 2019-05-08      0
1 2019-05-08 2019-05-15      0
2 2019-05-15 2019-05-22      4
3 2019-05-22 2019-05-29     12
4 2019-05-29 2019-06-05      0

谢谢，杰兹-我需要对实例的预订价值求和，我该怎么做？
z = zip(daterange_df['week_start'], daterange_df['week_end'])
daterange_df['count'] = [parking_master['Exit_Date'].between(s, e).sum() for s, e in z]
print (daterange_df)
  week_start   week_end  count
0 2019-05-01 2019-05-08      0
1 2019-05-08 2019-05-15      0
2 2019-05-15 2019-05-22      4
3 2019-05-22 2019-05-29     12
4 2019-05-29 2019-06-05      0
