有没有办法将所有键转换为小写？注意:dict末尾有一个空格.

我有一个dict,我想使用simplejson转换为JSON.

如何确保我的dict的所有键都是小写的？

    {
        "DISTANCE": 17.059918745802999, 
        "name": "Foo Bar", 
        "Restaurant": {
            "name": "Foo Bar", 
            "full_address": {
                "country": "France", 
                "street": "Foo Bar", 
                "zip_code": "68190", 
                "city": "UNGERSHEIM"
            }, 
            "phone": "+33.389624300", 
            "longitude": "7.3064454", 
            "latitude": "47.8769091", 
            "id": "538"
        }, 
        "price": "", 
        "composition": "", 
        "profils": {}, 
        "type_menu": "", 
        "ID": ""
    },

编辑:谢谢大家看看我的问题,对不起,我没有详细解释为什么我想要这个.这是修补JSONEmitter的django-piston.
