Python | Pandas tseries.offsets.DateOffset.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.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.




# importing pandas as pd
import pandas as pd
  
# importing the to_offset function
from pandas.tseries.frequencies import to_offset
  
# Creating Timestamp
ts = pd.Timestamp('2019-10-10 07:15:11')
  
# Create the DateOffset of 2 day
do = to_offset(freq = '2D')
  
# Print the Timestamp
print(ts)
  
# Print the DateOffset
print(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.




# Adding the dateoffset to the given timestamp
new_timestamp = ts + do
  
# Print the updated timestamp
print(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 not
print(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.




# importing pandas as pd
import pandas as pd
  
# importing the to_offset function
from pandas.tseries.frequencies import to_offset
  
# Creating Timestamp
ts = pd.Timestamp('2019-10-10 07:15:11')
  
# Create the DateOffset
do = to_offset(freq = '10D2H')
  
# Print the Timestamp
print(ts)
  
# Print the DateOffset
print(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.




# Adding the dateoffset to the given timestamp
new_timestamp = ts + do
  
# Print the updated timestamp
print(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 not
print(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.
