Return a Timestream with a substring between the start and end indices.

Parameters:

  • start (Optional[int], default: None)

    The inclusive index to start at. None indicates the beginning

    of the string. Negative indices count backwards from the end of

    the string.

  • end (Optional[int], default: None)

    The exclusive index to end at. None indicates the length of

    the string. Negative indices count backwards from the end of

    the string.

Notes
