You can use the Shapely Python module to parse WKT geometry and extract the coordinates.

Try this:

import shapely.wkt

shapes = [ 'MULTIPOLYGON (((69.0 41.0, 69.0 41.4, 69.4 41.4, 69.4 41.0, 69.0 41.0)), ((59.0 42.0, 59.0 42.4, 59.4 42.4, 59.4 42.0, 59.0 42.0)))' ]

for shape in shapes:
  shapelyObject = shapely.wkt.loads(shape)
  for polygon in shapelyObject:
      coords = list(polygon.exterior.coords)
      print(coords)

Output:

[(69.0, 41.0), (69.0, 41.4), (69.4, 41.4), (69.4, 41.0), (69.0, 41.0)]
[(59.0, 42.0), (59.0, 42.4), (59.4, 42.4), (59.4, 42.0), (59.0, 42.0)]
