Python | Pandas tseries.offsets.CustomBusinessDay.copy

| |

DateOffsets can be created to move dates by a specified 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 with a valid date, it is first moved to a valid date and then an offset is created.

tseries.offsets.CustomBusinessDay.copy() Pandas tseries.offsets.CustomBusinessDay.copy() creates a copy of this offset object.

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

Parameter: None

Returns: copy

Example # 1: Use pandas.tseries.offsets.CustomBusinessDay.rollforward () to create a copy of this offset object.

# import pandas as pd

import pandas as pd

 
# Create a label in timestamp

ts = pd.Timestamp ( ’2019-4-23 11: 15: 00’ )

 
# Create offset

cbd = pd.tseries.offsets.CustomBusinessDay (weekmask = ’Mon Tue Wed’ )

  
# Print time stamp

print (ts)

 
# Print offset

print (cbd)

Logout:

Now we will add an offset to the given timestamp object to increase the datetime value. We’ll also create a copy of this offset object.

# Adds an offset to the specified timestamp

new_timestamp = ts + cbd

 
# Print updated timestamp

print (new_timestamp)

  
# Now create a copy of this offset object.

cbd_copy = cbd.copy ()

 
# check if the copies match

print (cbd_copy is cbd)

Output:

As we can see in the output, we have successfully created an offset and added it to the given timestamp. We’ve also created a copy of this offset object.

Example # 2: Use pandas.tseries.offsets.CustomBusinessDay.rollforward () to create a copy of this object offsets.

# import pandas as pd

import pandas as pd

 
# Create a timestamp

ts = pd.Timestamp ( ’2019-4-23 11: 15: 00’ )

 
# Create offset

cbd = pd.tseries.offsets.CustomBusinessDay (n = 3 , weekmask = ’Mon Tue Wed Thu’ )

  
# Print time stamp

print (ts)

 
# Print offset

print (cbd)

Output:

We will now add an offset to this timestamp object to increase the datetime value. We’ll also create a copy of this offset object.

# Adds an offset to the specified timestamp

new_timestamp = ts + cbd

 
# Print updated timestamp

print (new_timestamp)

  
# Now create a copy of this offset object.

cbd_copy = cbd.copy ()

 
# check if the copies match

print (cbd_copy is cbd)

Output:

As we can see in the output, we have successfully created an offset and added it to the given timestamp. We’ve also created a copy of this offset object.
