How can I extract Name of Label with python?

Thank yu @Dmitrii for your tip. Unfortunately, the Handle_TDataStd_Name is not found / cannot be imported from OCC.Core.TDataStd.

from OCC.Core.TDataStd import TDataStd_Name, Handle_TDataStd_Name
ImportError: cannot import name 'Handle_TDataStd_Name' from 'OCC.Core.TDataStd'

Well, I do not know whether I am using the proper class for handle or not. :-(

Following is my full code:

from OCC.Core.STEPCAFControl import STEPCAFControl_Reader
from OCC.Core.TDocStd import TDocStd_Document
from OCC.Core.TDF import TDF_LabelSequence
from OCC.Core.XCAFDoc import XCAFDoc_DocumentTool
from OCC.Core.TDataStd import TDataStd_Name, Handle_TDataStd_Name

def read_step_and_print_names(step_file_path):
    try:
        doc = TDocStd_Document("pythonocc-doc")

        # Get the shape tool for accessing shapes in the document
        shape_tool = XCAFDoc_DocumentTool.ShapeTool(doc.Main())

        # Read the STEP file into the document
        reader = STEPCAFControl_Reader()
        reader.SetColorMode(True)
        reader.SetNameMode(True)
        reader.SetLayerMode(True)

        if reader.ReadFile(step_file_path) != 1:
            print("Error: Unable to read STEP file.")
            return

        if not reader.Transfer(doc):
            print("Error: Unable to transfer STEP data to document.")
            return

        # Get all labels containing shapes
        labels = TDF_LabelSequence()
        shape_tool.GetFreeShapes(labels)

        # Iterate through all labels and print their names
        for i in range(labels.Length()):
            label = labels.Value(i + 1)  # Labels are 1-indexed
            if label.IsNull():
                print("Null label encountered, skipping...")
                continue

            # Use FindAttribute to check for and retrieve the name attribute
            name_attr = Handle_TDataStd_Name()
            if label.FindAttribute(TDataStd_Name.GetID(), name_attr):
                name = name_attr.Get()
                print(f"Shape Name: {name}")
            else:
                print("Unnamed Shape")
    except Exception as e:
        print(f"An error occurred: {e}")

# Example usage with a local STEP file path
step_file_path = "./tests/data/dummy.stp"
read_step_and_print_names(step_file_path)

Thank you for your info. How can I find RWMesh Class? As I remember, there is a Package namely e.g. `OCC.Core.RWMesh`.
