首先从http://pypi.python.org/pypi/python-json下载python-json, 然后安装。

解压zip然后把json.py minjson.py 拷到 /usr/lib/python2.5/下面就行了。

怎样使用请看:http://docs.python.org/library/json.html

或者如下简单例子:

    import json  

    s = '[{"name":"niaochao","point":{"lat":"39.990","lng":"116.397"},"desc":"aoyunhuizhuchangdi"},{"name":"beidapingpangqiuguan","point":{"lat":"39.988","lng":"116.315"},"desc":"pingpangqiubisaichangdi"},{"name":"beijinggongrentiyuchang","point":{"lat":"39.930","lng":"116.446"},"desc":"zuqiubisaichangdi"}]'  

    locations = json.read(s)  

    print str(len(locations))  

    for location in locations:  

        print location["name"]  

        print location["point"]["lat"]
- EOF -
