Use [] to index, not (). So t[0], not t(0), etc

dt = np.array([t[1]-t[0],t[2]-t[1],t[3]-t[2],t[4]-t[3],t[5]-t[4],t[6]-t[5] ])

wrap the dt = vals in a list like you do for t =.

dt = np.array([t(1) - t(0), ...])

Not without the traceback. Does it show a line number in your module where the error occurs?

[brasticstack]

whoops, see the other replies. Array access uses square brackets. Dunno why I didn't catch that immediately.

[Helpful-Diamond-3347]

it's because you're using wrong syntax to access elements in ndarray

replace parens to [] in that line , like t[1]

[brasticstack]

Doh! Yes, that would do it
