Python Pandas - How to perform ceil operation on the DateTimeIndex with microseconds frequency
To perform ceil operation on the DateTimeIndex with microseconds frequency, use the DateTimeIndex.ceil() method. For microseconds frequency, use the freq parameter with value ‘us’.
At first, import the required libraries −
import pandas as pd
Create a DatetimeIndex with period 5 and frequency as S i.e. seconds −
datetimeindex = pd.date_range('2021-10-18 07:20:32.261811624', periods=5,
tz='Australia/Adelaide', freq='40S')Display DateTimeIndex −
print("DateTimeIndex...\n", datetimeindex)
Perform Ceil operation on DateTimeIndex date with microseconds frequency. For microseconds frequency, we have used 'us' −
print("\nPerforming ceil operation with microseconds frequency...\n",
datetimeindex.ceil(freq='us'))Example
Following is the code −
import pandas as pd
# DatetimeIndex with period 5 and frequency as S i.e. seconds
# timezone is Australia/Adelaide
datetimeindex = pd.date_range('2021-10-18 07:20:32.261811624', periods=5,
tz='Australia/Adelaide', freq='40S')
# display DateTimeIndex
print("DateTimeIndex...\n", datetimeindex)
# display DateTimeIndex frequency
print("DateTimeIndex frequency...\n", datetimeindex.freq)
# Ceil operation on DateTimeIndex date with microseconds frequency
# For microseconds frequency, we have used 'us'
print("\nPerforming ceil operation with microseconds frequency...\n",
datetimeindex.ceil(freq='us'))Output
This will produce the following code −
DateTimeIndex... DatetimeIndex(['2021-10-18 07:20:32.261811624+10:30', '2021-10-18 07:21:12.261811624+10:30', '2021-10-18 07:21:52.261811624+10:30', '2021-10-18 07:22:32.261811624+10:30', '2021-10-18 07:23:12.261811624+10:30'], dtype='datetime64[ns, Australia/Adelaide]', freq='40S') DateTimeIndex frequency... <40 * Seconds> Performing ceil operation with microseconds frequency... DatetimeIndex(['2021-10-18 07:20:32.261812+10:30', '2021-10-18 07:21:12.261812+10:30', '2021-10-18 07:21:52.261812+10:30', '2021-10-18 07:22:32.261812+10:30', '2021-10-18 07:23:12.261812+10:30'], dtype='datetime64[ns, Australia/Adelaide]', freq=None)
