Script in the Notes not working?

user:~/catkin_ws/src/mathsrobotics/unit2_exercises$ python vector.py

Traceback (most recent call last):

File “vector.py”, line 5, in

vectors = [np.array((4,2)),np,array((-3,3)),np.array((-2,2))]

NameError: name ‘array’ is not defined

Hello @drvsiva,

It looks like you introduced an error when you pasted the code to your script, in this line:

`vectors = [np.array((4,2)),np,array((-3,3)),np.array((-2,2))]`

It is not `np,array((-3,3)`

but `np.array((-3,3)`

(with a dot).

Best,
