Python | Pandas tseries.offsets.CustomBusinessHour.copy

  • Last Updated : 23 Apr, 2019

Dateoffsets are a standard kind of date increment used for a date range in Pandas. It works exactly like relativedelta in terms of the keyword args we pass in. DateOffets work as follows, each offset specify a set of dates that conform to the DateOffset. For example, Bday defines this set to be the set of dates that are weekdays (M-F).

DateOffsets can be created to move dates forward a given number of valid dates. For example, Bday(2) can be added to a date to move it two business days forward. If the date does not start on a valid date, first it is moved to a valid date and then offset is created.

Pandas tseries.offsets.CustomBusinessHour.copy() function is used to create a copy of the given offset object.

Syntax: pandas.tseries.offsets.CustomBusinessHour.copy()

Parameter : None

Returns : create a copy of the offset object

Example #1: Use pandas.tseries.offsets.CustomBusinessHour.copy() function to create a copy of the given offset object.




# importing pandas as pd
import pandas as pd
  
# Creating Timestamp
ts = pd.Timestamp('2019-4-23 11:15:00')
  
# Create an offset
cbh = pd.tseries.offsets.CustomBusinessHour(n = 2, weekmask = 'Mon Tue Wed Thu',
                                           start ='12:00')
  
# Print the Timestamp
print(ts)
  
# Print the Offset
print(cbh)

Output :

Now we will add the offset to the given timestamp object to increment the datetime value. We will also create a copy of the given offset object.




# Adding the offset to the given timestamp
new_timestamp = ts + cbh
  
# Print the updated timestamp
print(new_timestamp)
  
# create a copy
cbh_copy = cbh.copy()
  
# check if the two objects are same
print(cbh_copy is cbh)

Output :



As we can see in the output, we have successfully created an offset and added it to the given timestamp. We have also checked if the two objects are same or not.

Example #2: Use pandas.tseries.offsets.CustomBusinessHour.copy() function to create a copy of the given offset object.




# importing pandas as pd
import pandas as pd
  
# Creating Timestamp
ts = pd.Timestamp('2019-4-23 11:15:00')
  
# Create an offset
cbh = pd.tseries.offsets.CustomBusinessHour(start ='07:00', end ='14:00')
  
# Print the Timestamp
print(ts)
  
# Print the Offset
print(cbh)

Output :

Now we will add the offset to the given timestamp object to increment the datetime value. We will also create a copy of the given offset object.




# Adding the offset to the given timestamp
new_timestamp = ts + cbh
  
# Print the updated timestamp
print(new_timestamp)
  
# create a copy
cbh_copy = cbh.copy()
  
# check if the two objects are same
print(cbh_copy is cbh)

Output :

As we can see in the output, we have successfully created an offset and added it to the given timestamp. We have also checked if the two objects are same or not.
