Python | Pandas TimedeltaIndex.delete

Pandas TimedeltaIndex is a type of index used for representing the numeric indices that are used in the Timedelta objects. The TimedeltaIndex is used for performing operations on the time delta values. In this article, we will discuss how to delete rows from a TimedeltaIndex in a DataFrame using the TimedeltaIndex.delete() method.

Syntax of Pandas TimedeltaIndex.delete()

TimedeltaIndex.delete(locs)

The TimedeltaIndex.delete() method accepts the following parameters:

• locs: The integer location of the row(s) to be deleted.

pandas.TimedeltaIndex.delete() Parameters

The list of parameters that the TimedeltaIndex.delete() method accepts are as follows:

• locs: The integer location(s) of the row(s) to be deleted.

Example

Let's take a look at an example to understand how to delete rows from a TimedeltaIndex in a DataFrame using the TimedeltaIndex.delete() method.

# Importing the pandas and numpy modules
import pandas as pd
import numpy as np

# Creating a Timedelta object
td = pd.to_timedelta(np.arange(10), unit='h')

# Creating a DataFrame with TimedeltaIndex
df = pd.DataFrame(index=td, data=np.random.randn(10, 3), columns=['A', 'B', 'C'])

# Printing the DataFrame
print("Original DataFrame:")
print(df)

# Deleting the 5th and 7th rows from the DataFrame
df = df.drop(td[[5, 7]])

# Printing the modified DataFrame
print("\nModified DataFrame:")
print(df)

Output:

Original DataFrame:
                       A         B         C
00:00:00       2.597527  0.660604  0.899168

04:00:00      -1.046532  0.201160  0.353821
05:00:00      -0.051053 -0.125471 -1.912983
06:00:00      -0.263322 -0.767397 -0.247813
07:00:00      -0.596925  2.573221 -0.723517
08:00:00      -1.403888 -0.591854 -0.514790
09:00:00       0.290097 -1.381086  1.116879

Modified DataFrame:
                       A         B         C
00:00:00       2.597527  0.660604  0.899168
01:00:00      -1.416047 -0.315819 -0.696008
02:00:00       0.225790  1.180094  1.787335
03:00:00       0.432413  0.999857 -1.684780
04:00:00      -1.046532  0.201160  0.353821
06:00:00      -0.263322 -0.767397 -0.247813
08:00:00      -1.403888 -0.591854 -0.514790
09:00:00       0.290097 -1.381086  1.116879

In the above example, we have created a Timedelta object with hourly values and then created a DataFrame with TimedeltaIndex and random data. We have then deleted the 5th and 7th rows from the DataFrame using the TimedeltaIndex.delete() method.

Conclusion

The TimedeltaIndex.delete() method of the Pandas library is used for deleting rows from a TimedeltaIndex in a DataFrame. This method can be used to perform operations on the Timedelta values of DataFrame.
