Python | Pandas TimedeltaIndex.insert

In pandas, TimedeltaIndex represents an immutable array of time delta values, which can be used as an axis in a DataFrame or Series for representing differences in time.

The insert method of TimedeltaIndex is used to insert a new timedelta value at a particular position without modifying the original index.

Here's how you can use the insert method:

import pandas as pd # Create a TimedeltaIndex tdi = pd.TimedeltaIndex(['1 days', '3 days', '4 days']) # Insert a new timedelta at the second position (0-based index) new_tdi = tdi.insert(1, pd.Timedelta('2 days')) print(new_tdi)

Output:

TimedeltaIndex(['1 days', '2 days', '3 days', '4 days'], dtype='timedelta64[ns]', freq=None)

In the above code:

  1. We first created a TimedeltaIndex with values: 1 day, 3 days, and 4 days.
  2. We then used the insert method to insert '2 days' at the second position.
  3. The result is a new TimedeltaIndex with values: 1 day, 2 days, 3 days, and 4 days.

Note that the insert method returns a new TimedeltaIndex object and does not modify the original one, as TimedeltaIndex is immutable.
