目前我这样做：
def getJSONString(lst):
join = ""
rs = "{"
for i in lst:
rs += join + '"' + str(i[0]) + '":"' + str(i[1]) + '"'
join = ","
return rs + "}"
我称之为：
rs = getJSONString([("name", "value"), ("name2", "value2")])
它不需要嵌套（它只是一个简单的名称值对列表）。但我愿意以不同的方式调用函数。这一切看起来有点笨拙，有更优雅的方式吗？这需要在2.x下运行。
请注意，这不是重复：Python - convert list of tuples to string（除非可以修改该答案以创建JSON字符串作为输出）。
编辑：将名称值对作为字典传递会更好吗？
有一种更好的方法来生成JSON字符串：json module。
import json
rs = json.dumps(dict(lst))
这利用了dict()可以采用一系列键值对（双值元组）并将其转换为映射的事实，json模块直接将其转换为JSON对象结构。
示范：
>>> import json
>>> lst = [("name", "value"), ("name2", "value2")]
>>> rs = json.dumps(dict(lst))
>>> print rs
{"name2": "value2", "name": "value"}
(lambda lst: json.dumps({item[0]:item[1] for item in lst}))([(1,2), (3,4)])
您可以转换为一个完整的json内容
