Python | Pandas PeriodIndex.hour

  • 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 PeriodIndex.hour attribute return the hour of the period for the given PeriodIndex object.

Syntax : PeriodIndex.hour

Parameters : None

Return : Index object containing hour values.



Example #1: Use PeriodIndex.hour attribute to find the hour value of the period for the given PeriodIndex object.




# importing pandas as pd
import pandas as pd
  
# Create the PeriodIndex object
pidx = pd.PeriodIndex(start ='2005-12-21 08:45 '
              end ='2005-12-21 11:55', freq ='H')
  
# Print the PeriodIndex object
print(pidx)

Output :

Now we will use the PeriodIndex.hour attribute to find the hour of the period in the given object.




# return the hour value
pidx.hour

Output :

As we can see in the output, the PeriodIndex.hour attribute has returned an index object containing the hour values for each element of the give PeriodIndex object.
 
Example #2: Use PeriodIndex.hour attribute to find the hour of the period for the given PeriodIndex object.




# importing pandas as pd
import pandas as pd
  
# Create the PeriodIndex object
pidx = pd.PeriodIndex(start ='2011-02-1'
           end ='2011-02-14', freq ='D')
  
# Print the PeriodIndex object
print(pidx)

Output :



Now we will use the PeriodIndex.hour attribute to find the hour value of the period in the given object.




# return the hour value
pidx.hour

Output :

As we can see in the output, the PeriodIndex.hour attribute has returned an index object containing the hour values for each element of the give PeriodIndex object. As we can see the for the pidx object that we have applied daily frequency. So, the hour value is not set and hence the function has returned 0 for all the elements.
