New question #631918 on Sikuli:
https://answers.launchpad.net/sikuli/+question/631918

I tried to rename an existing file in sikuli using a batch command but get the following error:

TypeError: unsupported operand type(s) for +: 'NoneType' and 'list'
using this code:

import subprocess
from time import gmtime, strftime
now = strftime("%Y-%m-%d_%H:%M:%S", gmtime())
src = "C:\Users\Murph\xxx_yyy_.jpg"
dst = "xxx_yyy_zzz_" + now + "_.jpg"
subprocess.call('ren %s %s'%(src,dst), shell=True)
then I tried a different code and got this error: SyntaxError: ("no viable alternative at input ''%s''",

different code:

import os 
os.system(ren '%s','%s' < %(src,dst))
What am I missing?

error code1:
