Removed a simple pitfall case of a consider-using-in case

[NaelsonDouglas]

Problem: The code was incurring into the consider-using-in pitfall case, as described by Pylint documentation here https://github.com/vald-phoenix/pylint-errors/blob/master/plerr/errors/refactoring/R1714.md

Solution: Applied adequate refactoring. Only a single line of code was changed
