蟒蛇找到重复的词典中的列表和合并

Question

我使用Python 2.7 我的问题是一样的python list of dictionaries find duplicates based on value 除了我我的唯一标识符基于多个键（ID，姓名，地址等）

而且，基于这些键我必须合并一些其他值

任何建议？

谢谢

那么一点点的帮助，我得到了这段代码

uq_map = {} 
for rec in outputs: 
    #Set values that are marked as unique identifiers 
    key = rec["o_date"], rec["o_hour"], rec["co_name"], rec["o_student"], rec["o_class"], rec["o_day"] 
    #If they exist we append them to a new defined key 
    if key in uq_map: 
     item = uq_map[key] 
     print "item ",item 
     item['o_teacher_set'].append(rec["o_teacher"]) 
     item['o_location_set'].append(rec["o_location"])    
    #if not we insert them into new key    
    else: 
     item = rec.copy() 
     item['o_teacher_set'] = [rec["o_teacher"]] 
     item['o_location_set'] = [rec["o_location"]] 
     uq_map[key] = item 


print uq_map 
#This is the loop to remove duplicates from nwe keys 
for rec in uq_map.values(): 
    print 'Teachers: ', '+'.join(set(rec['o_teacher_set'])) 

如果有任何更Python solutons请让我知道
