Python | Pandas TimedeltaIndex.round
  • Last Updated : 06 Jan, 2019

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 TimedeltaIndex.round() function round the labels of the given TimedeltaIndex object to the specified frequency.

Syntax : TimedeltaIndex.round(freq, *args, **kwargs)

Parameters :
freq : freq string/object

Return : index of same type



Example #1: Use TimedeltaIndex.round() function to round the labels of the given TimedeltaIndex object.




# importing pandas as pd
import pandas as pd
  
# Create the TimedeltaIndex object
tidx = pd.TimedeltaIndex(data =['06:05:01.000030', None, '22 day 2 min 3us 10ns',
                     '+23:59:59.999999', None, '+12:19:59.999999'], name ='Old')
  
# Print the TimedeltaIndex object
print(tidx)

Output :

Now we will use the TimedeltaIndex.round() function to round the labels of the tidx object to minutely frequency.




# round the labels of the tidx
# object to minutely frequency
tidx.round('T')

Output :

As we can see in the output, the TimedeltaIndex.round() function has rounded off the value of the given TimedeltaIndex object to the desired frequency.
 
Example #2: Use TimedeltaIndex.round() function to rename the given TimedeltaIndex object.




# importing pandas as pd
import pandas as pd
  
# Create the TimedeltaIndex object
tidx = pd.TimedeltaIndex(data =[None, '1 days 06:05:01.000030', None,
                                '1 days 02:00:00', '21 days 06:15:01.000030'],
                                                           name ='Old_object')
  
# Print the TimedeltaIndex object
print(tidx)

Output :

Now we will use the TimedeltaIndex.round() function to round the labels of the tidx object to daily frequency.




# round the labels of the tidx 
# object to daily frequency
tidx.round('D')

Output :

As we can see in the output, the TimedeltaIndex.round() function has rounded off the value of the given TimedeltaIndex object to the desired frequency.
