How to create a shapely Polygon from a list of shapely Points?


If you specifically want to construct your Polygon from the shapely geometry Points, then call their x, y properties in a list comprehension. In other words:

from shapely import geometrypoly = geometry.Polygon([[p.x, p.y] for p in pointList])print(poly.wkt)  # prints: 'POLYGON ((0 0, 1 0, 1 1, 0 1, 0 0))'

Note that shapely is clever enough to close the polygon on your behalf, i.e. you don't necessarily have to pass-in the first point again at the end.


A Polygon object requires a nested list of numbers, not a list of Point objects.

polygon = Polygon([[0, 0], [1, 0], [1, 1], [0, 1]])


In version 1.7a2 they have fixed this.

The code in question will just work.
