03 - Class Vector

Create vectorclass.py module implementing a Vector class with the following methods:

class Vector:
    def __init__(self,x):
        """
        constructor of the Vector class
        input:
        x - list or tuple of lenght
        sets:
        self.x - tuple: the vector values
        self.n - vector length
        >>> v = Vector([1,2,3])
        """
 
    def scaled_copy(self,scale):
        """

        >>> v.x

        :return: Vector object result of the addition, None if not possible (not compatible vectors)
