'Polygon' object has no attribute 'shape'

This error occurs when trying to access the 'shape' attribute of a 'Polygon' object in a programming language such as Python. The 'shape' attribute is not a built-in attribute of the 'Polygon' object, and therefore cannot be accessed.
To fix this error, you need to use the correct attribute or method to access the shape of the polygon object. Depending on the programming language and library you are using, this may involve using a different method or attribute to access the polygon's shape, such as 'boundary', 'vertices', or 'coords'.
For example, in the Python library 'shapely', you can use the 'boundary' attribute of a 'Polygon' object to access its shape:
```
from shapely.geometry import Polygon
# Create a polygon object
polygon = Polygon([(0, 0), (0, 1), (1, 1), (1, 0)])
# Access the polygon's shape using the boundary attribute
shape = polygon.boundary
print(shape)
```
Output:
```
LINESTRING (0 0, 0 1, 1 1, 1 0, 0 0)
```
By using the correct attribute or method to access the shape of a 'Polygon' object, you can avoid the 'Polygon' object has no attribute 'shape' error.
