Python | Pandas Series.dt.is_year_end

Series.dt can be used to access series values ​​as datetimelike and return multiple properties. Series.dt.is_year_end Pandas Series.dt.is_year_end returns a boolean value indicating whether the date is the last day year.

Syntax: Series.dt.is_year_end

Parameter: None

Returns: numpy array

Example # 1: Use the Series.dt.is_year_end attribute to check if whether the dates in the underlying data of this series object are the last day of the year.

# import pandas as pd import pandas as pd   # Create series sr = pd.Series ([ ’2012-12-31’ , ’ 2019-1-1 12: 30’ , ’2008-02-2 10:30’ , ’2010-1-1 09:25’ , ’2019-12-31 00:00’ ])   # Create index idx = [ ’Day 1’ , ’Day 2’ , ’ Day 3’ , ’Day 4’ , ’Day 5’ ]    # at set index sr.index = idx   # Convert baseline data to date and time sr = pd.to_datetime (sr)   # Print series print (sr)

Output:

Now we will use the Series.dt.is_year_end attribute to check if the dates in a given series object are the last day of the year or not.

# n check if dates are # last day of the year result = sr.dt.is_year_end   # print the result print (result)

Output:

As we can see in the output, the Series.dt.is_year_end attribute successfully accessed and returned a boolean indicating whether the dates are the last day of the year or not.

Example # 2: Use the Series.dt.is_year_end attribute to check if dates in the underlying data of this series object are the last day of the year.

# import pandas as pd import pandas as pd   # Create series sr = pd.Series (pd.date_range ( ’2012-12-31 00:00’ , periods = 5 , freq = ’D’ ))    # Create index idx = [ ’ Day 1’ , ’Day 2’ , ’Day 3’ , ’ Day 4’ , ’Day 5’ ]    # set index sr.index = idx    # Print series print (sr)

Output:

We will now use the Series.dt.is_year_end attribute to check if whether the dates in this series object are the last day of the year or not.

# check if the dates are # last day of the year result = sr.dt.is_year_end    # print the result print (result)

Exit:

As we can see in the output, the Series.dt.is_year_end successfully accessed and returned boolean values ​​indicating whether the dates are the last day of the year or not.
