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()])
