Python | Pandas TimedeltaIndex.shift()

  • Last Updated : 01 Jan, 2019

Python is a great language for doing data analysis, primarily because of the fantastic ecosystem of data-centric python packages. Pandas is one of those packages and makes importing and analyzing data much easier.

Pandas TimedeltaIndex.shift() function performs specialized shift on the given TimedeltaIndex object, which produces a DatetimeIndex object.

Syntax : TimedeltaIndex.shift(n, freq=None)

Parameters :
n : Periods to shift by
freq : DateOffset or timedelta-like, optional

Return : shifted : DatetimeIndex

Example #1: Use TimedeltaIndex.shift() function to shift the given TimedeltaIndex object by 2 periods.




# importing pandas as pd
import pandas as pd
  
# Create the TimedeltaIndex object
tidx = pd.TimedeltaIndex(start ='11 days 22:14:12.001124',
                                   periods = 5, freq ='T')
  
# Print the TimedeltaIndex object
print(tidx)

Output :

Now we will use the TimedeltaIndex.shift() function to shift each element of the given TimedeltaIndex object by 2 periods.




# shift by 2 periods
tidx.shift(n = 2)

Output :

As we can see in the output, the TimedeltaIndex.shift() function has returned a new object and it has shifted each element by 2 minutes.

Example #2: Use TimedeltaIndex.shift() function to shift the given TimedeltaIndex object by 2 periods.




# importing pandas as pd
import pandas as pd
  
# Create the TimedeltaIndex object
tidx = pd.TimedeltaIndex(start ='03 days 09:22:56',
                            periods = 5, freq ='H')
  
# Print the TimedeltaIndex object
print(tidx)

Output :

Now we will use the TimedeltaIndex.shift() function to shift each element of the given TimedeltaIndex object by 5 periods.




# shift by 5 periods
tidx.shift(n = 5)

Output :

As we can see in the output, the TimedeltaIndex.shift() function has returned a new object and it has shifted each element by 5 hours.
