如何更改我在 arcpy 中的符号系统以获得清晰的轮廓点？

Question

I am not sure why my arcpy result's point outline is not changing to clear in ArcGIS Pro. Everything else works, except for the outline syntax. Is there anything wrong with my syntax or this may be a ArcPro bug?

`#Add spatial join layer to the current map
p = arcpy.mp.ArcGISProject('CURRENT')
m = p.listMaps('CompTool')[0]
layer = Stream_Comp.getOutput(0)
m.addDataFromPath(layer)

#Format symbology rendering 
l = m.listLayers(StreamComp_Name)[0]
sym = l.symbology


if sym.renderer.type == 'SimpleRenderer':
    sym.updateRenderer('GraduatedColorsRenderer')
    sym.renderer.classificationField = Comp_Field
    sym.renderer.classificationMethod = 'NaturalBreaks'
    sym.renderer.breakCount = 7


#Updating Symbology Rendering - error:nothing happens to the symbol outline     
for brk in sym.renderer.classBreaks:
    brk.symbol.size = 6
    brk.symbol.outlineColor = {'RGB' : [0, 0, 0, 0]}`

I'm not sure if you put it there by mistake, but you have a " ' " at the end of your brk.symbol.outlineColor line. Not sure if it's in your code or not, but if that single quote is there, you're probably getting a mismatched quotes syntax error.
