Series.dt can be used to access the values of the series as datetimelike and return several properties. Pandas Series.dt.weekofyear attribute return a numpy array containing the week ordinal of the year in the underlying data of the given series object.
Syntax: Series.dt.weekofyear
Parameter : None
Returns : numpy array
Example #1: Use Series.dt.weekofyear attribute to return the week ordinal of the year 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.weekofyear attribute to return the week ordinal of the year in the underlying data of the given Series object.
# return the week ordinal # of the year result = sr.dt.weekofyear   # print the result print(result) |
Output :
As we can see in the output, the Series.dt.weekofyear attribute has successfully accessed and returned the week ordinal of the year in the underlying data of the given series object.
Â
Example #2 : Use Series.dt.weekofyear attribute to return the week ordinal of the year 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.weekofyear attribute to return the week ordinal of the year in the underlying data of the given Series object.
# return the week ordinal # of the year result = sr.dt.weekofyear   # print the result print(result) |
Output :
As we can see in the output, the Series.dt.weekofyear attribute has successfully accessed and returned the week ordinal of the year in the underlying data of the given series object.
