I’m looking at my code for the v_corrected formula ( v_corrected[“db” + str(l)] = … and can’t find what the syntax issue is. I realize that it might be in the previous statement but I’m not sure what is wrong as the syntax check does not give a good idea. Since I can’t share the code of the previous statement I’ll try to describe it like this:
(1 - (np.power(beta1,t)) This is the expression of the denominator of the previous formula. Maybe I’m parameterizing something wrong in the np.power?
When you can’t find a syntax error in python, it means you are looking in the wrong place. 
The problem is not on that line. The problem is that the previous line is incomplete. You are probably missing a close parentheses or close bracket. The notebook editor is syntax aware: click on a paren and it will highlight the matching one. Or not. 
Just in that expression you show, there are 3 open parens, but only 2 close parens, right?
Yes, something was missing, which is odd as I really thought I looked this over many times. Now it works, Thx a lot.

It’s easy to miss the parenthesis matching thing just looking at it. The key is using the editor to help in the matching.
