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 DatetimeIndex.ceil()
function ceil the data to the specified frequency. The function takes the target frequency as input. It returns a new DatetimeIndex object.
Syntax: DatetimeIndex.ceil(freq)
Parameters :
freq : The frequency level to ceil the index to. Must be a fixed frequency like ‘S’ (second) not ‘ME’ (month end)
Return : Index of the same type for a DatetimeIndex or TimedeltaIndex, or a Series with the same index for a Series
Example #1: Use DatetimeIndex.ceil()
function to ceil the data of the DatetimeIndex object to the specified frequency.
import pandas as pd
didx = pd.DatetimeIndex(start = '2000-01-15 08:00' , freq = 'S' , periods = 4 )
print (didx)
|
Output :
Now we want to ceil the second based frequency of the DatetimeIndex object to minute based frequency
Output :
As we can see in the output, the function has returned the ceiling values of the DatetimeIndex object.
Example #2: Use DatetimeIndex.ceil()
function to ceil the data of the DatetimeIndex object to the specified frequency.
import pandas as pd
didx = pd.DatetimeIndex(start = '2018-11-15 09:45' , freq = 'T' , periods = 5 )
print (didx)
|
Output :
Now we want to ceil the minute based frequency of the DatetimeIndex object to hour based frequency
Output :
As we can see in the output, the function has ceil the values of the DatetimeIndex object to the desired frequency.
