Please create new field with "Double"

Value

raka()

Code Block

rec=0
def raka():
global rec
pStart = 1201
pInterval = 1
if (rec == 0):
rec = pStart
else:
rec += pInterval
return rec

You could use itertools.count

Expression:

next(counter)

Code block:

import itertools
counter = itertools.count(start=1201)
