| 769 | |
| 770 | This is an efficient representation for sets consisting of several |
| 771 | continuous ranges, e.g. 1-100,200-400,402-1000 is represented |
| 772 | internally as a list of three pairs: [(1,100), (200,400), |
| 773 | (402,1000)]. The internal representation is always kept normalized. |
| 774 | |
| 775 | The constructor has up to three arguments: |
| 776 | - the string used to initialize the set (default ''), |
| 777 | - the separator between ranges (default ',') |
| 778 | - the separator between begin and end of a range (default '-') |
| 779 | The separators must be strings (not regexprs) and should be different. |
| 780 | |
| 781 | The tostring() function yields a string that can be passed to another |
| 782 | IntSet constructor; __repr__() is a valid IntSet constructor itself. |
| 783 | """ |
| 784 | |
