Pandas tseries offsets CustomBusinessMonthBegin function is

Pandas tseries offsets CustomBusinessMonthBegin function is_anchored() in Python

The Pandas tseries offsets CustomBusinessMonthBegin function is_anchored() used to determine whether the frequency is a unit frequency where n = 1. It returns a boolean value that specifies whether an unit frequency value is 1.

Syntax

 1 CustomBusinessMonthBegin.is_anchored()

is_anchored() function

 1 import pandas as pd
 2 
 3 # with default unit frequency
 4 offset = pd.tseries.offsets.CustomBusinessMonthBegin()
 5 res = offset.is_anchored()
 6 print(f'Does unit frequency is 1 : {res}')
 7 
 8 # with unit frequency as 1
 9 offset1 = pd.tseries.offsets.CustomBusinessMonthBegin(n = 1)
 10 res1 = offset1.is_anchored()
 11 print(f'Does unit frequency is 1 : {res1}')
 12 
 13 # with unit frequency is not 1
 14 offset2 = pd.tseries.offsets.CustomBusinessMonthBegin(n = 4)
 15 res2 = offset2.is_anchored()
 16 print(f'Does unit frequency is 1 : {res2}')

In the above example, a CustomBusinessMonthBegin objects are created with and without unit frequency. A is_anchored() function is called that determine whether the unit frequency is 1. The result is assign to the variable that will be printed on console.

Output

 1 Does unit frequency is 1 : True
 2 Does unit frequency is 1 : True
 3 Does unit frequency is 1 : False

Example 2

 1 import pandas as pd
 2 
 3 offset = pd.tseries.offsets.CustomBusinessMonthBegin(normalize = True)
 4 res = offset.is_anchored()
 5 print(f'Does unit frequency is 1 : {res}')

In the above example, a CustomBusinessMonthBegin objects are created without unit frequency and normalize as true. A is_anchored() function is called that determine whether the unit frequency is 1.

Output

 1 Does unit frequency is 1 : True

Example 3

 1 import pandas as pd
 2 
 3 offset1 = pd.tseries.offsets.CustomBusinessMonthBegin(n = 3, normalize = True)
 4 res1 = offset1.is_anchored()
 5 print(f'Does unit frequency is 1 : {res1}')

In the above example, a CustomBusinessMonthBegin objects are created with unit frequency and normalize as true. A is_anchored() function is called that determine whether the unit frequency is 1.
