For example, page numbers, only starting at zero. The syntax is like what you would put between brackets [ ]. The slice is one of the few Python types that can't be subclassed, but this class converts to and from slices, and allows similar use. - PageRange(str) parses a string representing a page range. - PageRange(slice) directly "imports" a slice. - to_slice() gives the equivalent slice. - str() and repr() allow printing. - indices(n) is like slice.indices(n). argreturnNct|tr||_yt|tr|j |_yt|t xrt jt|}|s t||jdr8t|jd}|dk7r|dznd}t|||_yt|jdddDcgc]}|r t|ndc}|_ycc}w)a Initialize with either a slice -- giving the equivalent page range, or a PageRange object -- making a copy, or a string like "int", "[int]:[int]" or "[int]:[int]:[int]", where the brackets indicate optional ints. Remember, page indices start with zero. Page range expression examples: : all pages. -1 last page. 22 just the 23rd page. :-1 all but the last page. 0:3 the first three pages. -2 second-to-last page. :3 the first three pages. -2: last two pages. 5: from the sixth page onward. -3:-1 third & second to last. The third, "stride" or "step" number is also recognized. ::2 0 2 4 ... to the end. 3:0:-1 3 2 1 but not 0. 1:10:2 1 3 5 7 9 2::-1 2 1 0. ::-1 all pages in reverse order. Note the difference between this notation and arguments to slice(): slice(3) means the first three pages; PageRange("3") means the range of only the fourth page. However PageRange(slice(3)) means the first three pages.
