How to create a Python dictionary with double quotes as default quote format?

couples = [
               ['jack', 'ilena'], 
               ['arun', 'maya'], 
               ['hari', 'aradhana'], 
               ['bill', 'samantha']]
pairs = dict(couples)

print pairs的结果为：

{'arun': 'maya', 'bill': 'samantha', 'jack': 'ilena', 'hari': 'aradhana'}

方法一：

import json
json.dumps(pairs)

方法二：

print '{%s}' % ', '.join(['"%s": "%s"' % (k, v) for k, v in pairs.items()])
