Python | Pandas Series.dt.is_quarter_start
Series.dt can be used to access the values of the series as datetimelike and return several properties. Pandas Series.dt.is_quarter_start attribute return a boolean value Indicating whether the date is the first day of a quarter.
Syntax: Series.dt.is_quarter_start
Parameter : None
Returns : numpy array
Example #1: Use Series.dt.is_quarter_start attribute to check if the dates in the underlying data of the given series object is the first day of the quarter.
# importing pandas as pd import pandas as pd # Creating the Series sr = pd.Series(['2012-4-1', '2019-7-18 12:30', '2008-02-2 10:30', '2010-4-22 09:25', '2019-1-1 00:00']) # 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.is_quarter_start attribute to check if the dates in the given series object is the first day of the quarter or not.
# check if dates are the first # day of the quarter result = sr.dt.is_quarter_start # print the result print(result) |
Output :
As we can see in the output, the Series.dt.is_quarter_start attribute has successfully accessed and returned boolean values indicating whether the dates are the first day of the quarter or not.
Example #2 : Use Series.dt.is_quarter_start attribute to check if the dates in the underlying data of the given series object is the first day of the quarter.
# importing pandas as pd import pandas as pd # Creating the Series sr = pd.Series(pd.date_range('2012-4-1 00:00', periods = 5, freq = 'W')) # 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.is_quarter_start attribute to check if the dates in the given series object is the first day of the quarter or not.
# check if dates are the first # day of the quarter result = sr.dt.is_quarter_start # print the result print(result) |
Output :
As we can see in the output, the Series.dt.is_quarter_start attribute has successfully accessed and returned boolean values indicating whether the dates are the first day of the quarter or not.
