Using Bpy to Access UV Map Data

I am new to Python but know C++. I want to access a UV Map and iterate through it to determine if a section of the grid contains UV information or not. In essence I want to be able to translate the UV Map coordinates such that I can write them to a JSON file.

Not exactly sure what you’re asking for- but if you need to access UV data for an object it’s done through the MeshUVLoopLayer in object mode (or a BMLoop in edit mode).

as an example, this will print out all of the UV coordinates of the first UV layer on your object:

for loop in my_object.data.uv_layers[0].data:
    print(loop.uv)
