Creating Shapely LineString from two Points

Question

If have two points, from which I want to create a straight LineString object:

from shapely.geometry import Point, LineString
A = Point(0,0)
B = Point(1,1)

The Shapely manual for LineString states:

A sequence of Point instances is not a valid constructor parameter. A LineString is described by points, but is not composed of Point instances.

So if I have two points A and B, is there a shorter/better/easier way of creating a line AB than my current "best" guess...

AB = LineString(tuple(A.coords) + tuple(B.coords))

... which looks rather complicated. Is there an easier way?

---

With Shapely 1.3.2, the above statement from the manual is no longer correct. So from now on,

AB = LineString([A, B])

works!

Answer 1

Since Shapely 1.3, you can create a LineString from Points:

>>> from shapely.geometry import Point, LineString
>>> LineString([Point(0, 0), Point(1, 1)]).wkt
'LINESTRING (0 0, 1 1)'

Apologies for the contradiction in the manual.

Answer 2

The base method is:

AB = LineString([(A.x,A.y), (B.x,B.y)])

You can also use slicing to concatenate the coordinate lists:

AB = LineString(A.coords[:] + B.coords[:])
