Python | Pandas TimedeltaIndex.slice_indexer

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.slice_indexer() function compute the slice indexer for input labels and step for an ordered TimedeltaIndex object. The function assumes that the data is sorted.

Syntax : TimedeltaIndex.slice_indexer(start=None, end=None, step=None, kind=None)

Parameters :
start : If None, defaults to the beginning
end : If None, defaults to the end
step : int, default None
kind : string, default None

Return : indexer : ndarray or slice

Example #1: Use TimedeltaIndex.slice_indexer() function to compute the slice indexer for the passed label in the given TimedeltaIndex object.

# importing pandas as pd
import pandas as pd

# Create the TimedeltaIndex object
tidx = pd.TimedeltaIndex(start ='11 days 22:14:12.001124',
                                   periods = 5, freq ='T')

# Print the TimedeltaIndex object
print(tidx)

Output :

Now we will use the TimedeltaIndex.slice_indexer() function to find the slice value for the passed labels.

# find the slice indexer
tidx.slice_indexer('11 days 22:15:20.001124')

Output :

As we can see in the output, the TimedeltaIndex.slice_indexer() function has returned the position as well as the number of elements in the tidx object.

Example #2: Use TimedeltaIndex.slice_indexer() function to compute the slice indexer for the passed label in the given TimedeltaIndex object.

# importing pandas as pd
import pandas as pd

# Create the TimedeltaIndex object
tidx = pd.TimedeltaIndex(start ='03 days 09:22:56',
                            periods = 5, freq ='H')

# Print the TimedeltaIndex object
print(tidx)

Output :

Now we will use the TimedeltaIndex.slice_indexer() function to find the slice value for the passed labels.

# find the slice indexer
tidx.slice_indexer('3 days 12:20:56')

Output :

As we can see in the output, the TimedeltaIndex.slice_indexer() function has returned the position as well as the number of elements in the tidx object.
