Python Pandas - 从 TimeDeltaIndex 中提取每个元素的天数


若要从 TimeDeltaIndex 对象中提取每个元素的天数,请使用TimedeltaIndex.days 属性。

首先,导入需要的库 −

import pandas as pd

创建 TimeDeltaIndex 对象。我们已经使用 'data' 参数将类 timedelta 的数据设置好 −

tdIndex = pd.TimedeltaIndex(data =['10 day 5h 2 min 3us 10ns', '+22:39:19.999999',
'2 day 4h 03:08:02.000045', '+21:15:45.999999'])

显示 TimedeltaIndex −

print("TimedeltaIndex...\n", tdIndex)

显示 TimeDeltaIndex 中每个元素的天数 −

print("\nThe number of days from the TimeDeltaIndex object...\n", tdIndex.days)

示例

代码如下 −

import pandas as pd

# Create a TimeDeltaIndex object
# We have set the timedelta-like data using the 'data' parameter as well
tdIndex = pd.TimedeltaIndex(data =['10 day 5h 2 min 3us 10ns', '+22:39:19.999999',
'2 day 4h 03:08:02.000045', '+21:15:45.999999'])

# display TimedeltaIndex
print("TimedeltaIndex...\n", tdIndex)

# display the number of days from each element of TimeDeltaIndex
print("\nThe number of days from the TimeDeltaIndex object...\n", tdIndex.days)

# Return a dataframe of the components of TimeDeltas
print("\nThe Dataframe of the components of TimeDeltas...\n", tdIndex.components)

输出

将产生以下代码 −

TimedeltaIndex...
TimedeltaIndex(['10 days 05:02:00.000003010', '0 days 22:39:19.999999',
'2 days 07:08:02.000045', '0 days 21:15:45.999999'],
dtype='timedelta64[ns]', freq=None)

The number of days from the TimeDeltaIndex object...
Int64Index([10, 0, 2, 0], dtype='int64')

The Dataframe of the components of TimeDeltas...
      days hours  minutes seconds milliseconds microseconds nanoseconds
 0    10    5         2       0      0          3               10
 1    0     22        39      19     999        999              0
 2    2      7        8       2      0          45               0
 3    0     21        15      45     999        999              0
