How to loop over a generator that returns multiple output?

I am a beginner in Python and I have a following question regarding a generator. My generator yields three variables:

def generate():
    for i in range(1, 10):
        j = i + 1
        k = i ** 2
        yield i, j, k

In the following function, I would like to loop over the variable j only. Of course, this works:

for var_i, var_j, var_k in generate():
    print("This is my varible j: ", var_j)

But I have two unused variables here - var_i, var_k. So I would like to ask, if there is a better way, how to do this?

This answer did not help me: Looping through a generator that returns multiple values Thanks a lot.

The convention is to use _ as a variable when you're not interested in using the value.

for _, var_j, _ in generate():
