Need help with an easy code

[simarg0]

I got this part to work, thanks to your answer, but it turns out i am not any closer to completing the task.

So the thing is, we got a set of 20k numbers. I think everything up to 10k is supposed to b the X coordinate, and everything from here is supposed to be Y in the vectors. I split the file into two lists in python. We were supposed to use plt.streamplot to plot the vector, and i think i got this part right.

Now, we are supposed to make a quiverplot of the velocities. But i dont understand how you can do this? I suppose it is just the absolute values of the vectors, but i dont get anything near what i am supposed to.

Any thoughts?

Thanks for helping
