Pandas tseries offsets QuarterBegin function is_month_end() in Python
The Pandas tseries offsets QuarterBegin function is_month_end() used to determine whether the timestamp occurs on the month end. It returns a boolean value that specifies whether the timestamp occurs at the end of quarter month.
Syntax
 1 QuarterBegin.is_month_end()
is_month_end() function
 1 import pandas as pd
 2 
 3 offset = pd.tseries.offsets.QuarterBegin()
 4 
 5 tstamp = pd.Timestamp(2022, 6, 30)
 6 res = offset.is_month_end(tstamp)
 7 print(f'Timestamp at quarter month end :{res}')
 8 
 9 tstamp1 = pd.Timestamp(2022, 5, 30)
 10 res1 = offset.is_month_end(tstamp1)
 11 print(f'Timestamp at quarter month end :{res1}')
In the above example, a Timestamp created by passing a date value. A is_month_end() function is called that determine whether a timestamp occurs at the end of quarter month. The result is assign to the variable that will be printed on console.
Output
 1 Timestamp at quarter month end :True
 2 Timestamp at quarter month end :False

Example 2

Example 2
 1 import pandas as pd
 2 
 3 tstamp = pd.Timestamp(2023, 4, 30)
 4 print('The timestamp object :', tstamp)
 5 
 6 offset = pd.tseries.offsets.QuarterBegin(normalize = True)
 7 res = offset.is_month_end(tstamp)
 8 print(f'Timestamp at quarter month end :{res}')
In the above example, a Timestamp created by passing a date value and QuarterBegin object with normalize as true. A is_month_end() function is called that determine whether a timestamp occurs at the end of quarter month.
Output
 1 The timestamp object : 2023-04-30 00:00:00
 2 Timestamp at quarter month end :True

Example 3

Example 3
 1 import pandas as pd
 2 
 3 tstamp1 = pd.Timestamp(2024, 5, 31)
 4 print('The timestamp object :', tstamp1)
 5 
 6 offset1 = pd.tseries.offsets.QuarterBegin(n = 3, startingMonth = 4, normalize = True)
 7 res1 = offset1.is_month_end(tstamp1)
 8 print(f'Timestamp at quarter month end :{res}')
In the above example, a Timestamp created by passing a date value and QuarterBegin object with normalize as true, unit frequency as 3 and startingMonth as 4. A is_month_end() function is called that determine whether a timestamp occurs at the end of quarter month.
Output
 1 The timestamp object : 2024-05-31 00:00:00
 2 Timestamp at quarter month end :True
