Hello everyone!

Have you ever wished that instead of having to have your users use annoying function names like getSelection() or setSelection(), they could just use a property that did it all for them? No more user function calling. Welcome to the future, or at least the unknown past.

Here is a demo of the built-in property function:

class Vector:
	def __init__(self, x, y, z):
		self.x = x
		self.y = y
		self.z = z

	def __repr__(self):
		return "(%.2f, %.2f, %.2f)"%(self.x, self.y, self.z)

	def get_mag(self):
		return (self.x**2+self.y**2+self.z**2)

	magnitude = property(get_mag)

vec = Vector(1,2,3)

print('vec initialized at:')
print(vec)
print('magnitude=', vec.magnitude, '\n') # == 14

vec.x = 10
print('vec.x = 10')
print(vec)
print('magnitude=', vec.magnitude, '\n') # == 113

vec.y = -5
print('vec.y = -5')
print(vec)
print('magnitude=', vec.magnitude, '\n') # == 134

I’m glad I could share this with you, and sorry for not posting in so long.

Happy coding!
