sequence generator in prepare receipe

[Obireddy]

Hi Team,

Good Morning.

I want add new column to dataset where I need to fill data as unique sequence data combination of both string and numbers like AB1,AB2,AB3, XYZ1,XYZ2,YX1 like.

How can I add new column with data like above.

Thanks in advance.

Use a Prepare recipe and Formula processor. You can combine other column values.

Here is the python code 

Import pandas as pd

def alpha_sequence(n):
   return ['ab' + str(i) for i in range(1, n+1)]

n = 10000
sequence = alpha_sequence(n)
df = pd.DataFrame(sequence, columns=["Unique_id"])

How can I put this code in to prepare recipe, to generate sequence numbers for new column?
