python格式化dict输出

python格式化dict输出
如果dict里有unicode or utf-8编码的字符串，缺省是：
In [75]: dd = { 'name': u'功夫熊猫' }
In [76]: dd
Out[76]: {'name': u'\u529f\u592b\u718a\u732b'}

In [77]: dd2 = { 'name': '功夫熊猫' }
In [78]: dd2
Out[78]: {'name': '\xe5\x8a\x9f\xe5\xa4\xab\xe7\x86\x8a\xe7\x8c\xab'}

输出中文不直观，有一种方法是把dict转化成josn格式的字符串输出
print simplejson.dumps(dd, ensure_ascii=False)
这种方法的缺点是不太美观
现在介绍另一种方法

#coding=utf-8import pprint, cStringIOclass UniPrinter(pprint.PrettyPrinter):            def format(self, obj, context, maxlevels, level):        if isinstance(obj, unicode):            out = cStringIO.StringIO()            out.write('u"')            for c in obj:                if ord(c)<32 or c in u'"\\':                    out.write('\\x%.2x' % ord(c))                else:                    out.write(c.encode("utf-8"))                            out.write('"')            # result, readable, recursive            return out.getvalue(), True, False        elif isinstance(obj, str):            out = cStringIO.StringIO()            out.write('"')            for c in obj:                if ord(c)<32 or c in '"\\':                    out.write('\\x%.2x' % ord(c))                else:                    out.write(c)                            out.write('"')            # result, readable, recursive            return out.getvalue(), True, False        else:            return pprint.PrettyPrinter.format(self, obj,                context,                maxlevels,                level)        #UniPrinter().pprint({ u'k"e\\y': u'我爱ä¸*国人' })print { 'name': u'功夫熊猫' }UniPrinter().pprint({ 'name': u'功夫熊猫' })UniPrinter().pprint({'name': '\xe5\x8a\x9f\xe5\xa4\xab\xe7\x86\x8a\xe7\x8c\xab'})UniPrinter().pprint({'name':'\xe5\x8a\x9f\xe5\xa4\xab\xe7\x86\x8a\xe7\x8c\xab', 'age':22, 'address':'yydg.com.cn', 'male':True})
