Python is a great language for doing data analysis, primarily because of the fantastic ecosystem of data-centric python packages. Pandas is one of those packages and makes importing and analyzing data much easier.
Pandas TimedeltaIndex.union() function is a specialized union for TimedeltaIndex objects. It combines overlapping ranges with the same DateOffset, will be much faster than Index.union
Syntax : TimedeltaIndex.union(other)
Parameters :
other : TimedeltaIndex or array-like
Return : Index or TimedeltaIndex
Example #1: Use TimedeltaIndex.union() function to find the set union of two TimedeltaIndex objects.
Python3
import pandas as pd
tidx1 = pd.TimedeltaIndex(start = '11 days 22:11:12.001124' ,
periods = 5 , freq = 'T' , name = 'New_object' )
tidx2 = pd.TimedeltaIndex(start = '11 days 22:14:12.001124' ,
periods = 5 , freq = 'T' , name = 'New_object' )
print (tidx1)
print (tidx2)
|
Output :
Now we will use the TimedeltaIndex.union() function to find the set union of the two objects
Output :
As we can see in the output, the TimedeltaIndex.union() function has returned an object which contains the union of both tidx1 and tidx2.
Example #2: Use TimedeltaIndex.union() function to find the set union of two TimedeltaIndex objects.
Python3
import pandas as pd
tidx1 = pd.TimedeltaIndex(start = '1 days 02:00:12.001124' ,
periods = 5 , freq = 'D' , name = 'Koala' )
tidx2 = pd.TimedeltaIndex(start = '3 days 02:00:12.001124' ,
periods = 5 , freq = 'D' , name = 'Koala' )
print (tidx1)
print (tidx2)

Output :
Now we will use the TimedeltaIndex.union() function to find the set union of the two objects
Output :
As we can see in the output, the TimedeltaIndex.union() function has returned an object which contains the union of both tidx1 and tidx2.
