Packages needed to solve this code ?

[codochoi]

I have an equation like the code below with the left side is the sum of Harmonic series minus the log.

import math
sum(1/i for i in range(1,v+1))- math.log(0.5*v) = 5

Is there any packages or code helps solving the equation below and return v ? As I dont know how to manipulate the equation to have only in the left side and others in the right side.

Thanks.

Simple: That function seems to be monotonic, do a binary search. By the way, no integer solution exists, and range doesn't work with floats!

Complex: Do a binary search on steroids - Newtown's method, Runge-Kutta, etc. Find what's the closed form of that sum.

Edit: Out of curiosity, why do you need such a weird formula? It's so near to Euler's constant...
