How to extent of the map view as an image format in arcgis pro to the same size as polygon's feature class?

From converting this code

import arcpy, os
aprx = arcpy.mp.ArcGISProject("CURRENT")
mv = aprx.activeView

# Change the extent of the map view
ext = mv.camera.getExtent()
ext.XMin = ext.XMin
ext.YMin = ext.YMin
ext.XMax = ext.XMax
ext.YMax = ext.YMax
mv.camera.setExtent(ext)
Output_File = os.path.join(arcpy.env.scratchFolder, 'ActiveMapView3.png')
mv.exportToPNG(Output_File, width=1000, height=1000)

I think you can just use the MapFrame class to do this.

 

import arcpy
aprx = arcpy.mp.ArcGISProject(r"C:\Projects\YosemiteNP\Yosemite.aprx")

m = aprx.listMaps("Yose*")[0]
lyr = m.listLayers("Ranger Stations")[0]
lyt = aprx.listLayouts("Main Attr*")[0]
mf = lyt.listElements("mapframe_element", "Yosemite National Park")[0]
mf.camera.setExtent(mf.getLayerExtent(lyr, False, True))

aprx.exportToPNG(out_png, {resolution}, {world_file}, {color_mode}, {embed_color_profile})
del aprx

I don't understand the coding of these 3 lines.

lyr = m.listLayers("Ranger Stations")[0]
lyt = aprx.listLayouts("Main Attr*")[0]
mf = lyt.listElements("mapframe_element", "Yosemite National Park")[0]

Those are from the example in the Docs.

lyr = m.listLayers("Ranger Stations")[0]  < replace with the name of the layer in your project that you want to get the extent from


lyt = aprx.listLayouts("Main Attr*")[0]  < replace with your layout name in your project


mf = lyt.listElements("mapframe_element", "Yosemite National Park")[0]  < replace 'Yosemite National Park' with your element name from your layout

Take a read of the Discussion in the docs.  It explains the Layout and ListElements methods.  MapFrame
