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. DateOffsets 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.DateOffset.copy() function returns a copy of the given DateOffset object.
Syntax: pandas.tseries.offsets.DateOffset.copy() Parameter : None Returns : copy of the given object
Example #1: Use pandas.tseries.offsets.DateOffset.copy() function to return a copy of the given DateOffset object.
Python3
# importing pandas as pdimport pandas as pd# importing the to_offset functionfrom pandas.tseries.frequencies import to_offset# Creating Timestampts = pd.Timestamp('2019-10-10 07:15:11')# Create the DateOffset of 2 daydo = to_offset(freq = '2D')# Print the Timestampprint(ts)# Print the DateOffsetprint(do) |
Output : 
Now we will add the dateoffset to the given timestamp object to increment the datetime value. We will also return a copy of the given DateOffset object.
Python3
# Adding the dateoffset to the given timestampnew_timestamp = ts + do# Print the updated timestampprint(new_timestamp)# Now we will create a copy of the given# DateOffset object.do_copy = do.copy()# Check if the two objects are same or notprint(do_copy is do) |
Output : As we can see in the output, the function has successfully created a copy of the given Dateoffset object. False indicates the two objects are not same. Example #2: Use pandas.tseries.offsets.DateOffset.copy() function to return a copy of the given DateOffset object.
Python3
# importing pandas as pdimport pandas as pd# importing the to_offset functionfrom pandas.tseries.frequencies import to_offset# Creating Timestampts = pd.Timestamp('2019-10-10 07:15:11')# Create the DateOffsetdo = to_offset(freq = '10D2H')# Print the Timestampprint(ts)# Print the DateOffsetprint(do) |
Output : Now we will add the dateoffset to the given timestamp object to increment the datetime value. We will also return a copy of the given DateOffset object.
