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.append() function appends a collection of index options together. More than one index object can be appended at a time by passing the indexes as a python list or tuple.
Syntax : TimedeltaIndex.append(other)
Parameters :
other : Index or list/tuple of indicesReturn : appended : Index
Example #1: Use TimedeltaIndex.append() function to append a TimedeltaIndex object at the end of the given object.
# importing pandas as pd import pandas as pd   # Create the first TimedeltaIndex object tidx1 = pd.TimedeltaIndex(start ='1 days 02:00:12.001124', periods = 5,                                               freq ='N', name ='Koala')   # Create the second TimedeltaIndex object tidx2 = pd.TimedeltaIndex(data =['-1 days 2 min 3us 10ns',                                  '1 days 06:05:01.000030',                                  '-1 days + 23:59:59.999999'])   # Print the first TimedeltaIndex object print(tidx1)   # Print the second TimedeltaIndex object print(tidx2) |
Output :
Now we will append tidx2 at the end of tidx1.
# append tidx2 at the end of tidx1 tidx1.append(tidx2) |
Output :
As we can see in the output, the TimedeltaIndex.append() function has appended tidx2 at the end of tidx1.

Example #2: Use TimedeltaIndex.append() function to append a list of TimedeltaIndex object at the end of the given object.
# importing pandas as pd import pandas as pd   # Create the first TimedeltaIndex object tidx1 = pd.TimedeltaIndex(start ='1 days 02:00:12.001124', periods = 5,                                               freq ='N', name ='Koala')   # Create the second TimedeltaIndex object tidx2 = pd.TimedeltaIndex(data =['-1 days 2 min 3us 10ns',                                  '1 days 06:05:01.000030',                                  '-1 days + 23:59:59.999999'])   # Create the third TimedeltaIndex object tidx3 = pd.TimedeltaIndex(data =['-3 days 02:10:00',                                  '1 days 06:05:01.000030',                                  '1 days 02:00:00'], name ='MyObjejct')   # Print the first TimedeltaIndex object print(tidx1)   # Print the second TimedeltaIndex object print(tidx2)   # Print the third TimedeltaIndex object print(tidx3) |
Output :
Now we will append tidx2 and tidx3 at the end of tidx1.
# append tidx2 and tidx3 at the end of tidx1 tidx1.append([tidx2, tidx3]) |
Output :
As we can see in the output, the TimedeltaIndex.append() function has appended tidx2 and tidx3 at the end of tidx1.
