Parameters ---------- columns : sequence of `Column` or a `ColDefs` The columns from which to create the table data. If these columns have data arrays attached that data may be used in initializing the new table. Otherwise the input columns will be used as a template for a new table with the requested number of rows. nrows : int Number of rows in the new table. If the input columns have data associated with them, the size of the largest input column is used. Otherwise the default is 0. fill : bool If `True`, will fill all cells with zeros or blanks. If `False`, copy the data from input, undefined cells will still be filled with zeros/blanks.

The two arrays must be the same size (though not necessarily the same shape). This is like an inplace version of `np.char.encode` though simpler since it's only limited to ASCII, and hence the size of each character is guaranteed to be 1 byte. If any strings are non-ASCII an UnicodeArrayEncodeError is raised--this is just a `UnicodeEncodeError` with an additional attribute for the index of the item that couldn't be encoded. rrNreadonly writeonlyallocate zerosize_ok) op_dtypesop_flagsflagsr!.r)rVrcrrgrnditeritemr%UnicodeEncodeError unravel_index iterindexroroperands) inarrayr out_dtyperritinitemoutitemrr)s r+rnrn<s;gm49;;W]=PQRRI hhy!! *I {J78H  #)h}o   B?! 9 9OFG!;;==//88GCLL 9 ??? w}==&UH)<>>? ;q>s42B'' C'11C""C'cd|jjD}td|DS)zN Returns True if any fields in a structured array have Unicode dtype. c3&K|] }|dV dS)rNr]r[ds r+ z&_has_unicode_fields..bs& 8 8qad 8 8 8 8 8 8r-c3,K|]}|jdkVdS)rN)rrs r+rz&_has_unicode_fields..cs(--qv}------r-)rcrjrany)rdtypess r+rr^sE9 8EK.5577 8 8 8F --f--- - --r-rA))rr4rrQ contextlibr functoolsrnumpyrVrr` astropy.utilsrrrr r r r r rrrrrrrrutilrrrrrer_rrrornrr]r-r+rs  ######&&&&&& >=========ppppppppfO9O9O9O9O9r{O9O9O9d$   1 D.....r-
