variable as byte

[jesshove]

I have been learning Python from 'Python for Everybody' by Charles Severance and found it very good
However, I have used his suggested code for downloading an image from a webpage and though I have checked it a few times and tried some alternatives, I always get a Traceback message

Error:
  fhand.write(picture)
TypeError: a bytes-like object is required, not 'int'

The ocde is copied below. Could some kind person please spot the mistake! Not sure if it's me or a misprint of course
Many thanks! Jessica

print(picture[:pos].decode())

#skip header and save picture data

picture = picture[pos+4]




fhand = open("stuff.jpg",'wb')
print("got this far")
fhand.write(picture)
fhand.close()
