In this matplotlib tutorial, we see:
x = np.arange(0, 2*np.pi, 0.01)
line, = ax.plot(x, np.sin(x))
Why is there an extra , after line is instantiated? I noticed that an error will be produced without the comma.
Initially, I thought that we were dropping the second item of two items that are being unpacked, although after running a, = (3,4) and getting an unpacking error I no longer believe that.
Thoughts?
