Python中的ujson模組

標籤：res   import   coding   python   *args   pre   imp   fun   結果   

聽說ujson比json模組快了很多，特來一試：

# -*- coding: utf-8 -*-import jsonimport ujsonimport timedef cost_time(func):    def inner(*args, **kwargs):        start_time = time.time()        result = func(*args, **kwargs)        stop_time = time.time()        print stop_time - start_time        # print result        return result    return innera = {}for i in xrange(1, 1000000):    a[i] = 1@cost_timedef json_dumps(obj):    return json.dumps(obj)@cost_timedef ujson_dumps(obj):    return ujson.dumps(obj)r1 = json_dumps(a)r2 = ujson_dumps(a)# 結果0.2451498508450.115290880203

果然快了一倍多
