Series.dt can be used to access the values of the series as datetimelike and return several properties. Pandas Series.dt.dayofweek attribute return the day of the week. It is assumed the week starts on Monday, which is denoted by 0 and ends on Sunday which is denoted by 6.
Syntax: Series.dt.dayofweek
Parameter : None
Returns : numpy array
Example #1: Use Series.dt.dayofweek attribute to return the day of week for the given 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', '2019-7-18 12:30', '2008-02-2 10:30', '2010-4-22 09:25', '2019-11-8 02:22']) # 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.dayofweek attribute to return the day of week for the given datetime in the underlying data of the given Series object.
# return the day of week result = sr.dt.dayofweek # print the result print(result) |
Output :
As we can see in the output, the Series.dt.dayofweek attribute has successfully accessed and returned the day of week in the underlying data of the given series object.
Example #2 : Use Series.dt.dayofweek attribute to return the day of week for the given 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 = 'M')) # 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.dayofweek attribute to return the day of week for the given datetime in the underlying data of the given Series object.
# return the day of week result = sr.dt.dayofweek # print the result print(result) |
Output :
As we can see in the output, the Series.dt.dayofweek attribute has successfully accessed and returned the day of week in the underlying data of the given series object.
