PYTHON:

The class name is VecGen

When you create the object, you will initiate it with a vector, i.e., this vector class contains one vector.

This class can calculate and return the distance between this vector and a given vector. If the other vector is not given or you can not calculate the distance, it returns its magnitudes.

# add your code below to design the class:

# test your code below (do not change the code below)

Vec1=VecGen([1,2,3,4,5])

Vec1.DisCal()

Vec1.DisCal([1,2,3])

Vec1.DisCal([4,5,6,7,8])
