title: Python Vector Class
body: <p>I'm coming from a C# background where this stuff is super easy—trying to translate into Python for Maya.</p>
  
  <p>There's gotta' be a better way to do this. Basically, I'm looking to create a Vector class that will simply have x, y and z coordinates, but it would be ideal if this class returned a tuple with all 3 coordinates and if you could edit the values of this tuple through x, y and z properties, somehow.</p>
  
  <p>This is what I have so far, but there <em>must</em> be a better way to do this than using an exec statement, right? I hate using exec statements.</p>
  
  <pre><code>class Vector(object):
      '''Creates a Maya vector/triple, having x, y and z coordinates as float values'''
  
      def __init__(self, x=0, y=0, z=0):
          self.x, self.y, self.z = x, y, z
  
      def attrsetter(attr):
          def set_float(self, value):
              setattr(self, attr, float(value))
          return set_float
  
      for xyz in 'xyz':
          exec("%s = property(fget=attrgetter('_%s'), fset=attrsetter('_%s'))" % (xyz, xyz, xyz))
  </code></pre>
