Points（点状几何要素）

class Point(coordinates)

The Point constructor takes positional coordinate values or point tuple parameters.

点的构造函数接受位置坐标值或点的元组参数。

>>> from shapely import Point
>>> point = Point(0.0, 0.0)
>>> q = Point((0.0, 0.0))

A Point has zero area and zero length.

点的面积、长度均为零。

>>> point.area
0.0
>>> point.length
0.0

Its x-y bounding box is a (minx, miny, maxx, maxy) tuple.

它的x-y边界是一个（minx, miny, maxx, maxy）元组。点的边界坐标就是点本身的坐标值。

>>> point.bounds
(0.0, 0.0, 0.0, 0.0)

Coordinate values are accessed via coords, x, y, and z properties.

坐标值通过coords、x、y和z属性访问。

>>> list(point.coords)
[(0.0, 0.0)]
>>> point.x
0.0
>>> point.y
0.0

Coordinates may also be sliced. New in version 1.2.14.

coords属性也支持切片操作。1.2.14版的新内容。

>>> point.coords[:]
[(0.0, 0.0)]

The Point constructor also accepts another Point instance, thereby making a copy.

点的构造函数也接受另一个点的实例，从而产生一个副本。

>>> Point(point)
<POINT (0 0)>
