shapely Accessing Data from Geometry collections

Question

I am new to shapely and python. I recently read Splitting Polygon by Linestring in GeoDjango? and below is the resulting answer.

from shapely import wkt
from shapely.ops import linemerge, unary_union, polygonize

POLY = "POLYGON ((34.67491149902344 31.59900710035676, 34.85000610351562 31.59900710035676, 34.85000610351562 31.73867905688433, 34.67491149902344 31.73867905688433, 34.67491149902344 31.59900710035676))"
LINE = "LINESTRING (34.64401245117188 31.63292168314889, 34.80812072753906 31.75911546882192)"

poly = wkt.loads(POLY)
line = wkt.loads(LINE)

merged = linemerge([poly.boundary, line])
borders = unary_union(merged)
polygons = polygonize(borders)
for p in polygons:
    print(p)

The print generates two polygon collections.

How do I access the arrays?

Answer 1

To get xy of polygon's vertices, use .exterior.xy property as demonstrated in the following code:

...
for p in polygons:
    print(p)
    # access arrays of the coordinates of the polygon
    xs, ys = p.exterior.xy[0], p.exterior.xy[1]
    # print all of xy's
    for ix, pp in enumerate(xs):
        print(ix, "(x,y): ", xs[ix], ys[ix])
