python 打印json格式的数据中文显示问题

通常会有这么一个应用场景，会用python去处理json格式的web API，以“ip.taobao.com”的API为例，详情见http://ip.taobao.com/instructions.php

是一个查询ip地址归属地的接口，其中包括国家、地区和ISP这些信息，均为中文显示。

我会用如下方式获取API数据：

myjson = json.loads(urllib.urlopen(url).read())

如上函数使用了urllib和json这2个模块，其中urllib用于请求页面获取json格式的数据；而json模块用于返回json格式数据；但是当你使用print来输出”myjson“这个变量的时候会发现中文全是unicode显示，可以用:

newjson = json.dumps(myjson, ensure_ascii=False)

让其显示成中文，默认是以ASCII来解析code的，中文不在ASCII编码当中，自然无法显示，可以看到json.dumps的帮助信息也说明了设为False后以：

>>> help(json.dumps)Help on function dumps in module json:dumps(obj, skipkeys=False, ensure_ascii=True, check_circular=True, allow_nan=Tre, cls=None, indent=None, separators=None, encoding='utf-8', default=None, **kw    Serialize ``obj`` to a JSON formatted ``str``.    If ``skipkeys`` is ``True`` then ``dict`` keys that are not basic types    (``str``, ``unicode``, ``int``, ``long``, ``float``, ``bool``, ``None``)    will be skipped instead of raising a ``TypeError``.    If ``ensure_ascii`` is ``False``, then the return value will be a    ``unicode`` instance subject to normal Python ``str`` to ``unicode``    coercion rules instead of being escaped to an ASCII ``str``.    If ``check_circular`` is ``False``, then the circular reference check    for container types will be skipped and a circular reference will    result in an ``OverflowError`` (or worse).    If ``allow_nan`` is ``False``, then it will be a ``ValueError`` to    serialize out of range ``float`` values (``nan``, ``inf``, ``-inf``) in    strict compliance of the JSON specification, instead of using the    JavaScript equivalents (``NaN``, ``Infinity``, ``-Infinity``).    If ``indent`` is a non-negative integer, then JSON array elements and    object members will be pretty-printed with that indent level. An indent    level of 0 will only insert newlines. ``None`` is the most compact    representation.    If ``separators`` is an ``(item_separator, dict_separator)`` tuple    then it will be used instead of the default ``(', ', ': ')`` separators.    ``(',', ':')`` is the most compact JSON representation.    ``encoding`` is the character encoding for str instances, default is UTF-8.    ``default(obj)`` is a function that should return a serializable version    of obj or raise TypeError. The default simply raises TypeError.    To use a custom ``JSONEncoder`` subclass (e.g. one that overrides the    ``.default()`` method to serialize additional types), specify it with    the ``cls`` kwarg.>>>

最后附图一张，可以看到显示中文正常了：
