Shapely is a Python library for geometric operations and manipulations. It allows you to create, analyze, and manipulate 2D and 3D geometric objects, such as points, lines, polygons, and more. You can perform various geometric operations like intersections, unions, buffers, and spatial analysis using Shapely.
Here's an example of how to use Shapely to create a point and a polygon:
```python
from shapely.geometry import Point, Polygon
# Create a point at coordinates (2, 3)
point = Point(2, 3)
# Create a polygon with vertices [(0, 0), (0, 5), (5, 5), (5, 0)]
polygon = Polygon([(0, 0), (0, 5), (5, 5), (5, 0)])
# Check if the point is inside the polygon
is_inside = point.within(polygon)
print(is_inside) # True
```
In this example, we create a Point object at coordinates (2, 3) and a Polygon object with vertices [(0, 0), (0, 5), (5, 5), (5, 0)]. We then use the `within` method to check if the point is inside the polygon. The result is `True` because the point lies within the polygon.
You can install Shapely using pip:
```
pip install shapely
```
I hope this helps! Let me know if you have any more questions.
