将班次数据(开始和结束时间)拆分为每小时数据 [英] unstacking shift data (start and end time) into hourly data
问题描述
我有一个 df 如下所示,它显示了一个人何时开始轮班、结束轮班、工作时间和工作日期.
I have a df as follows which shows when a person started a shift, ended a shift, the amount of hours and the date worked.
Business_Date Number PayTimeStart PayTimeEnd Hours
0 2019-05-24 1 2019-05-24 11:00:00 2019-05-24 12:15:00 1.250
1 2019-05-24 2 2019-05-24 12:30:00 2019-05-24 13:30:00 1.00
现在我要做的是将其分解为每小时格式,因此我知道 11:00 - 12:00 之间使用了多少小时
Now what I'm trying to do is break this into an hourly format, so I know how many hours were used between 11:00 - 12:00
因此,在我的脑海中,对于上述情况,我想将 11 - 12 之间的 1 小时放入 11:00 的 bin 中,并将剩余的 0.25 放入下一个 12 的 bin 中
so, in my head, for the above, I want to put the 1 hour between 11 - 12 into the bin for 11:00 and the remainder 0.25 into the next bin of 12
所以我最终会得到类似
so I would end up with something like
Business Date Time Hour
0 2019-05-24 11:00 1
1 2019-05-24 12:00 0.75
2 2019-05-24 13:00 0.5
推荐答案
一个想法是使用分钟 - 首先对 Series
使用列表理解和展平,然后按 hours
分组> 用 hour
s 来计数 GroupBy.size
并最后除以 60
最后几个小时:
One idea is working with minutes - first use list comprehension with flattening for Series
and then grouping by hours
with hour
s for count by GroupBy.size
and last divide by 60
for final hours:
s = pd.Series([z for x, y in zip(df['Pay Time Start'],
df['Pay Time End'] - pd.Timedelta(60, unit='s'))
for z in pd.date_range(x, y, freq='Min')])
df = (s.groupby([s.dt.date.rename('Business Date'), s.dt.hour.rename('Time')])
.size()
.div(60)
.reset_index(name='Hour'))
print (df)
Business Date Time Hour
0 2019-05-24 11 1.00
1 2019-05-24 12 0.75
2 2019-05-24 13 0.50
如果您需要按位置或 ID 分组
If you need to group by a location or ID
df1 = pd.DataFrame([(z, w) for x, y, w in zip(df['Pay Time Start'],
df['Pay Time End'] - pd.Timedelta(60, unit='s'),
df['Location']) for z in pd.date_range(x, y, freq='Min')],
columns=['Date','Location'])
df = (df1.groupby([df1['Date'].dt.date.rename('Business Date'),
df1['Date'].dt.hour.rename('Time'), df1['Location']])
.size() .div(60) .reset_index(name='Hour'))
