I would like to make a list of variables with two consecutive indices, example rr_10, rr_21 .. etc I tried :

n=3
rrL=list(var('rr_%d%d' %i %(i-1)) for i in [1..n])

without success:not enough arguments for format string what is the missing arguments here ?

I turned @nbruin's comment into an answer so you can accept it and mark the question as solved.

I would add an extra underscore to better separate the two indices in case they have several digits.
