Python Pandas - Get the hour of the period from the PeriodIndex object

To get the hour of the period from the PeriodIndex object, use the PeriodIndex.hour property.

At first, import the required libraries −

import pandas as pd

Create a PeriodIndex object. PeriodIndex is an immutable ndarray holding ordinal values indicating regular periods in time. We have set the frequency using the "freq" parameter −

periodIndex = pd.PeriodIndex(['2021-09-25 07:50:35', '2019-10-30 04:35:45',
'2021-07-15 02:25:15', '2022-06-25 09:20:55'], freq="T")

Display PeriodIndex object −

print("PeriodIndex...\n", periodIndex)

Display hour from the PeriodIndex object −

print("\nThe hour from the PeriodIndex object...\n", periodIndex.hour)

Example

Following is the code −

import pandas as pd

# Create a PeriodIndex object
# PeriodIndex is an immutable ndarray holding ordinal values indicating regular periods in time
# We have set the frequency using the "freq" parameter
periodIndex = pd.PeriodIndex(['2021-09-25 07:50:35', '2019-10-30 04:35:45',
'2021-07-15 02:25:15', '2022-06-25 09:20:55'], freq="T")

# Display PeriodIndex object
print("PeriodIndex...\n", periodIndex)

# Display PeriodIndex frequency
print("\nPeriodIndex frequency object...\n", periodIndex.freq)

# Display PeriodIndex frequency as string
print("\nPeriodIndex frequency object as a string...\n", periodIndex.freqstr)

# Display hour from the PeriodIndex object
print("\nThe hour from the PeriodIndex object...\n", periodIndex.hour)

Output

This will produce the following code −

PeriodIndex...
PeriodIndex(['2021-09-25 07:50', '2019-10-30 04:35', '2021-07-15 02:25', '2022-06-25 09:20'],
dtype='period[T]')

PeriodIndex frequency object...
<Minute>

PeriodIndex frequency object as a string...
T

The hour from the PeriodIndex object...
Int64Index([7, 4, 2, 9], dtype='int64')
