Metti alla prova le tue conoscenze sulla vita tumultuosa di Van Gogh, sulle sue opere vibranti ed emotive e sul suo profondo impatto sul mondo dell'arte.
I modified the above with one achievable sample. The validator ought to return Genuine

This isn't 100% satisfying to me -- having to do setup in both equally the metaclass and object class feels like it violates the DRY principle.
This point is been cleared by Many of us up there but Here's a direct place which I used to be seeking.
I used to be beating my head on this for rather some time right before finding what I believe is the answer. Python @Qualities certainly are a subset of descriptors, and, through the descriptor documentation (emphasis mine):
But python Homes enable code outside the class to generally be similar to Affordable rental property management system with instance variables. So code outside the house The category will not have to be changed when you incorporate a property, or have a simple occasion variable.
I am interested in how to use @property in Python. I've read the python docs and the instance there, for my part, is simply a toy code:
Tra le opere più celebri di Vincent van Gogh c'è una serie di dipinti che catturano la bellezza e la vivacità di un determinato fiore. Questi dipinti, notevoli for each i loro colori sorprendenti e le pennellate audaci, rimangono tra le sue opere più famose.
