Short algorithm problem. Criticize my work please :)

Problem: Given a query string: "name=larry&job=engineer" Convert query string to a python dict object where the dict's keys are query string's fields (value before the =) and the corresponding values are query string's values (value after the '=').

Expected result: {'name': 'larry', 'job': 'engineer'}

My solution:

def to_dict(s):
    r = dict()
    query = s.split("&")
    for item in query:
            q = item.split('=')
	    r[q[0]] = q[1]
    return r

How can I improve the solution above?
