Python | Pandas TimedeltaIndex.set_names
  • 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.set_names() function is used to set new names on the given TimedeltaIndex object. The function defaults to returning new index object.

Syntax : TimedeltaIndex.set_names(names, level=None, inplace=False)

Parameters :
names : name(s) to set
level : If the index is a MultiIndex (hierarchical), level(s) to set (None for all levels). Otherwise level must be None
inplace : if True, mutates in place

Return : new index (of same type and class…etc) [if inplace, returns None]



Example #1: Use TimedeltaIndex.set_names() function to set the names of the given TimedeltaIndex object.




# importing pandas as pd
import pandas as pd
  
# Create the TimedeltaIndex object
tidx = pd.TimedeltaIndex(start ='11 days 22:14:12.001124', periods = 5, freq ='T')
  
# Print the TimedeltaIndex object
print(tidx)

Output :

Now we will use the TimedeltaIndex.set_names() function to set the name of the given TimedeltaIndex object.




# set the name of the object
tidx.set_names(names ='Sale_Point')

Output :

As we can see in the output, the TimedeltaIndex.set_names() function has returned a new object and it has also set the name of the returned object.
 
Example #2: Use TimedeltaIndex.set_names() function to set the names of the given TimedeltaIndex object.




# importing pandas as pd
import pandas as pd
  
# Create the TimedeltaIndex object
tidx = pd.TimedeltaIndex(start ='03 days 09:22:56', periods = 5, freq ='H')
  
# Print the TimedeltaIndex object
print(tidx)

Output :

Now we will use the TimedeltaIndex.set_names() function to set the name of the given TimedeltaIndex object.




# set the name of the object
tidx.set_names(names ='Purchase_Time')

Output :

As we can see in the output, the TimedeltaIndex.set_names() function has returned a new object and it has also set the name of the returned object.
