this program should take two vectors as parameters, check if they are orthogonal and print "true"
if they are, or else print "false".
I should use docstrings too.

My code is pasted below, it runs smoothly and returns what I expect, but I am not sure how to include
docstrings in it.
I also wanted to ask, how come that when I define the dot product I am forced to write it this way (DotProduct = np.dot(V,W)) and this other way (V @ W) returns an error?

import numpy as np
from numpy import array
    
def v_vector(V):
  ##  return v /=np.linalg.norm(v)
    return (np.array(V))
def w_vector(W):
    return (np.array(W))

def test_ort(V,W):
    V=[1,0,-1]
    W=[1,sqrt(2),1]  
    DotProduct = np.dot(V,W)
    if DotProduct == 0:
        return True
    else:
        return False
  
print(test_ort(V,W))

doc strings

@ is not a valid tuple item separator, you must use ,
