Im having trouble figuiring this out in python

Problem 3 - pi2.py: Pi squared [15 points] Write a program that accepts an integer N as a command-line argument, and outputs the value (float) of the sum: N 1 1 1 1+ 22 1 z W + + + 1 N2 + 32 i2 i2 Remark: Unlike the harmonic sum, this series converges, specifically to 7/6. Therefore, it could be used as a way to numerically estimate 72. Practice goal: Simple summation accumulation
