問題在python比較不同的字典

Question

我有以下字典：

dict1=[{'code':'fgx23','number':23},{'code':'dx22a','number':2},{'code':'dsw23','number':10}] 

dict2=[{'code':'dx22a','number':9},{'code':'dsw23','number':1},{'code':'fgx23','number':20}] 

的問題是：如何添加具有相同的代碼

例如數字，在「dict1」代碼「 dx22a「的編號爲2，」dict2「的編碼爲」dx22a「的編號爲9，因此結果爲11。

幫助和感謝

Answer 1

dict1=[{'code':'fgx23','number':23},{'code':'dx22a','number':2},{'code':'dsw23','number':10}] 
dict2=[{'code':'dx22a','number':9},{'code':'dsw23','number':1},{'code':'fgx23','number':20}] 
consolidated = {i['code']:i['number'] for i in dict1} 
for i in dict2: 
    if i['code'] in consolidated: 
     consolidated[i['code']] += i['number'] 
    else: 
     consolidated[i['code']] = i['number'] 
print(consolidated) 

Answer 2

dict1=[{'code':'fgx23','number':23},{'code':'dx22a','number':2},{'code':'dsw23','number':10}] 
dict2=[{'code':'dx22a','number':9},{'code':'dsw23','number':1},{'code':'fgx23','number':20}] 
dict3 = [] 
for key, value in [(i['code'], i['number']) for i in dict1]: 
    for value2 in ([q['number'] for q in dict2 if q['code'] == key]): 
     dict3.append({'code': key,'number': value + value2}) 
print (dict3) 

這是假設你只想dict3有同時出現在dict1和dict2鍵。此外，您的預期輸出是與dict1和dict2（詞典列表）相同的格式。此外，dict1和dict2中的每個代碼中只有一個代碼。
