Python | Pandas TimedeltaIndex.append()

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 indices

Return : 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.
