columnize Format a simple (i.e. not nested) list into aligned columns. Return a list of strings as a compact set of columns arranged horizontally or vertically. For example, for a line width of 4 characters (arranged vertically): ['1', '2,', '3', '4'] => '1 3\n2 4\n' or arranged horizontally: ['1', '2,', '3', '4'] => '1 2\n3 4\n' Each column is only as wide as necessary. By default, columns are separated by two spaces - one was not legible enough. Set "colsep" to adjust the string separate columns. Set `displaywidth' to set the line width. Normally, consecutive items go down from the top to bottom from the left-most column to the right-most. If +arrange_vertical+ is set false, consecutive items will go across, left to right, top to bottom.
