Python is a great language for doing data analysis, primarily because of the fantastic ecosystem of data-centric python packages. Pandas is one of those packages and makes importing and analyzing data much easier.
Pandas DatetimeIndex.is_quarter_end attribute is an indicator for whether the date is the last day of a quarter. If the date is the last day of the quarter it returns True else it return False.
Syntax: DatetimeIndex.is_quarter_end
Returns: numpy array containing logical values.
Example #1: Use DatetimeIndex.is_quarter_end attribute to check if the dates present in the DatetimeIndex object is the last day of the quarter.
# importing pandas as pd import pandas as pd # Create the DatetimeIndex didx = pd.DatetimeIndex(['2014-01-31', '2014-04-30', '2017-03-31', '2000-12-02']) # Print the DatetimeIndex print(didx) |
Output :
Now we want to find if the dates contained in the given DatetimeIndex object is the last day of the quarter.
# find if the days are the last day of the quarter. didx.is_quarter_end |
Output :
As we can see in the output, the function has returned a numpy array containing logical values for each entry of the DatetimeIndex object. True values indicate the corresponding date was the last day of the quarter and False value indicate the corresponding date was not the last day of the quarter.
Example #2: Use DatetimeIndex.is_quarter_end attribute to check if the dates present in the DatetimeIndex object is the last day of the quarter.
# importing pandas as pd import pandas as pd # Create the DatetimeIndex idx = pd.date_range('2011-03-30', periods = 5) # Print the DatetimeIndex print(didx) |
Output :
Now we want to find if the dates contained in the given DatetimeIndex object is the last day of the quarter.
# find if the days are the last day of the quarter. didx.is_quarter_end |
Output :
As we can see in the output, the function has returned a numpy array containing logical values for each entry of the DatetimeIndex object. True values indicate the corresponding date was the last day of the quarter and False value indicate the corresponding date was not the last day of the quarter.
