Series.dt can be used to access the values of the series as datetimelike and return several properties. Pandas Series.dt.second attribute return a numpy array containing the second of the datetime in the underlying data of the given series object.
Syntax: Series.dt.second
Parameter : None
Returns : numpy array
Example #1:  Use Series.dt.second attribute to return the seconds of the datetime in the underlying data of the given Series object.
# importing pandas as pd import pandas as pd   # Creating the Series sr = pd.Series(['2012-10-21 09:30:45', '2019-7-18 12:30:21', '2008-02-2 10:30:38',                '2010-4-22 09:25:19', '2019-11-8 02:22:44'])   # Creating the index idx = ['Day 1', 'Day 2', 'Day 3', 'Day 4', 'Day 5']   # set the index sr.index = idx   # Convert the underlying data to datetime  sr = pd.to_datetime(sr)   # Print the series print(sr)  | 
Output : 
Now we will use Series.dt.second attribute to return the seconds of the datetime in the underlying data of the given Series object.
# return the second result = sr.dt.second   # print the result print(result)  | 
Output : 
As we can see in the output, the Series.dt.second attribute has successfully accessed and returned the second of the datetime in the underlying data of the given series object.
 
Example #2 :  Use Series.dt.second attribute to return the seconds of the datetime in the underlying data of the given Series object.
# importing pandas as pd import pandas as pd   # Creating the Series sr = pd.Series(pd.date_range('2012-12-12 12:12', periods = 5, freq = 'H'))   # Creating the index idx = ['Day 1', 'Day 2', 'Day 3', 'Day 4', 'Day 5']   # set the index sr.index = idx   # Print the series print(sr)  | 
Output : 
Now we will use Series.dt.second attribute to return the seconds of the datetime in the underlying data of the given Series object.
# return the second result = sr.dt.second   # print the result print(result)  | 
Output : 
As we can see in the output, the Series.dt.second attribute has successfully accessed and returned the second of the datetime in the underlying data of the given series object.
