Get the TypeError: list indices must be integers or slices, not range

It looks clear, if F is a list and ind is a range object, F[ind] is not a valid operation. It would be valid if ind was an integer or a slice object. Perhaps you meant F[:-1] instead of F[ind]?

@Gribouillis Thanks you yeah I find the mistake to change it F(:-1):
