os.environ is dictionnary so you can access to the keys
by the keys() method, and to the values by the values() method.

The values() method returns a list of values, so the k,v expression
doesn't match.

you can adapt your code like the following

for k in os.environ.keys():
    v = os.environ[k]
    print k,v
