This can also be achieved by accessing the LineStrings via list (multilinestring.coords).

However, it frequently causes issues in downstream applications thus is often rejected by APIs and tools. A common approach for removing the self-intersections is applying a zero-buffer operation (e.g. .buffer(0) in shapely). quotes for history
