TypeError: a bytes-like object is required, not 'str' in subprocess.check_output

Decode before using split funtion

Null,userprof = subprocess.check_output('set USERPROFILE', shell=True).decode('utf-8').split('=')

python python-3.x subprocess

Another solution is adding text=True to check_output:

path = os.getcwd().strip('/n') Null,userprof = subprocess.check_output('set USERPROFILE', shell=True, text=True).split('=')
