Removed a case of the manual indexer pitfall

[NaelsonDouglas]

Problem: There was a part on the code which was implemented using the manual iterator pitfall. It was detected using Pylint, under the code C0200. https://vald-phoenix.github.io/pylint-errors/plerr/errors/refactoring/C0200.html

Solution: Applied a simple refactoring to remove it.
