# import pandas as pd import pandas as pd   # Create DatetimeIndex didx = pd.DatetimeIndex ([ `2014-01-31` , ` 2014-04-30` , `2017-03-31` , `2000-12-02` ])   # Print DatetimeIndex print (didx)

Output:

Now we want to find out if the dates are contained in this DatetimeIndex object as the last day of the quarter.

# determine if days are the last day of the quarter. didx.is_quarter_end

Exit:

As we can see in the output, the function returned an empty array containing boolean values ​​for each entry in the DatetimeIndex object.  True values ​​indicate that the corresponding date was the last day of the quarter, and False values ​​indicate that the corresponding date was not the last day of the quarter.

Output:

As we can see in the output, the function returned an empty array containing boolean values ​​for each entry in the DatetimeIndex object.  True values ​​indicate that the corresponding date was the last day of the quarter, and False values ​​indicate that the corresponding date was not the last day of the quarter.
