i'm a beginner in python wen i apply thresholding i'm getting error

import SimpleITK as sitk
img = sitk.ReadImage("Sub1.png")
img=img>20

i'm getting error as

I applied img = sitk.Image(img.GetSize(), sitk.sitkUInt8)

but I'm getting a black image

Is there any option like double(img) or im2bw in python.Will normalize work?
