@Javier-Diaz-de-Rabago
this is not really a notepad++ question I guess, because npp,
as well as any other text editor on the planet
doesn’t care about what kind of python libraries you use.
There must be something wrong in your run configuration
if the same code runs under IDLE but don’t run if executed,
by whatever way you chose to execute, via npp.
