python - how can I use sympy to add expressions with index -

i have dataframe in pandas, first columns named x0 , second x1. has many(like 100) rows. have 100 groups of [x0,x1], , want generate long expression every related 1 group. more clearly, task want generate expression:

exp(b0*x00+b1*x10)+exp(b0*x01+b1*x11)+...exp(b0*(x0 100) + b1*(x1 100)) 

b0 , b1 both unknown value (symbols) here , find solution later on.

in brief, need expression sigma(exp(b0*x0+b1*x1)) , sigma has 100 items x0,x1 n dataframe, don't know how program loop.

please me.

i hope helps, i'm not familiar panda, need summation(f, (i, a, b)) sympy.

essentially, need declare expr = summation(exp, (i, 0, 101)) in case, 'exp' function has symbolic b0 , b1 terms inside it.

and when want pretty print out, need use pprint(expr) instead of print().
