If None, shape is defined from the shape of the first array in the list. formats : {None, sequence}, optional Sequence of formats for each individual field. If None, the formats will be autodetected by inspecting the fields and selecting the highest dtype possible. names : {None, sequence}, optional Sequence of the names of each field. fill_value : {None, sequence}, optional Sequence of data to be used as filling values.
