In this case to count integer divisors, given a specific predicate.</p> <hr> <h1 class="heading" id="context"> Context <a href="#context">#</a> </h1> <p>This semester I&rsquo;m doing a course on <a href="https://guiadoscursos.uab.pt/en/ucs/matematica-finita/">Discrete Mathematics</a>. I had an exercise to count integer divisors of a given number, which weren&rsquo;t divisible by another given number.</p> <p>To verify my reply, which involved a bit more of analysis, Python enabled me to write a quick script that could do it.</p>
