How can I use [for num in rang(a,b)] to do this function?

Using Python 3.8

Design a function called compute_harmonic_series that will take an integer n and computes and returns the sum of the harmonic series to n defined as: 1 + 1/2 + 1/3 + ... + 1 Your function should assume that n is not negative. Note, if n is 0, the function will return 0
