Python | Панды TimedeltaIndex.difference
Python - отличный язык для анализа данных, в первую очередь из-за фантастической экосистемы пакетов Python, ориентированных на данные. Pandas - один из таких пакетов, который значительно упрощает импорт и анализ данных.
Pandas TimedeltaIndex.difference() function return a new Index with elements from the index that are not in other. This is the set difference of two Index objects. It’s sorted if sorting is possible.
Syntax : TimedeltaIndex.difference(other)
Parameters :
other : Index or array-likeReturn : difference : Index
Example #1: Use TimedeltaIndex.difference() function to find the set difference of two TimedeltaIndex objects.
# importing pandas as pdimport pandas as pd # Create the first TimedeltaIndex objecttidx1 = pd.TimedeltaIndex(data =["06:05:01.000030", "+23:59:59.999999", "22 day 2 min 3us 10ns", "+23:29:59.999999", "+12:19:59.999999"]) # Create the seccond TimedeltaIndex objecttidx2 = pd.TimedeltaIndex(data =["09:11:18.000030", "+23:59:59.999999", "9 day 18 min 3us ", "+23:29:59.999999", "+12:19:59.999999"]) # Print the first and second TimedeltaIndex objectprint(tidx1, "
", tidx2) |
Выход : 
Now we will use the TimedeltaIndex.difference() function to find the set difference.
# find the set differencetidx1.difference(tidx2) |
Output :
As we can see in the output, the TimedeltaIndex.difference() function has returned a new object which contains only those elements which are unique to tidx1.
Example #2: Use TimedeltaIndex.difference() function to find the set difference of two TimedeltaIndex objects.
# importing pandas as pdimport pandas as pd # Create the first TimedeltaIndex objecttidx1 = pd.TimedeltaIndex(start ="1 days 02:00:12.001124", periods = 5, freq ="D", name ="Koala") # Create the second TimedeltaIndex objecttidx2 = pd.TimedeltaIndex(start ="3 days 02:00:12.001124", periods = 5, freq ="D", name ="Koala") # Print the first and second TimedeltaIndex objectprint(tidx1, "
", tidx2) |
Output :
Now we will use the TimedeltaIndex.difference() function to find the set difference.
# find the set differencetidx1.difference(tidx2) |
Output :
As we can see in the output, the TimedeltaIndex.difference() function has returned a new object which contains only those elements which are unique to tidx1.
