| 766 | |
| 767 | This is an efficient representation for sets consisting of several |
| 768 | continuous ranges, e.g. 1-100,200-400,402-1000 is represented |
| 769 | internally as a list of three pairs: [(1,100), (200,400), |
| 770 | (402,1000)]. The internal representation is always kept normalized. |
| 771 | |
| 772 | The constructor has up to three arguments: |
| 773 | - the string used to initialize the set (default ''), |
| 774 | - the separator between ranges (default ',') |
| 775 | - the separator between begin and end of a range (default '-') |
| 776 | The separators must be strings (not regexprs) and should be different. |
| 777 | |
| 778 | The tostring() function yields a string that can be passed to another |
| 779 | IntSet constructor; __repr__() is a valid IntSet constructor itself. |
| 780 | """ |
