python 關於傳遞Python字典參數的問題

Question

{
  "originProduct": {
      "statusType": "SALE",
      "saleType": "NEW",
      "leafCategoryId": "50002322",
      "name": "Jabra SPEAK 750 블루투스스피커/스피커폰/음성회의스피커폰/JABRA / 자브라 공식정품",
      "images": {
          "representativeImage": {
              "url": "http://shop1.phinf.naver.net/20221220_24/1671526069078ktTkT_JPEG/4172814067322311_1866531646.jpg"
          },
          "optionalImages": [
              {
                  "url": "http://shop1.phinf.naver.net/20221220_2/16715260691656YLKl_JPEG/4172814155176861_2054960625.jpg"
              },
              {
                  "url": "http://shop1.phinf.naver.net/20221220_5/1671526069249T4zWk_JPEG/4172814239069085_483270929.jpg"
              }
          ]
      }
}

我有一個像上面那樣的 json 文件。

def open(self):
    with open(self.json_file,"r",encoding='utf-8-sig') as f:
        item_dic=json.load(f)
    return item_dic

def save(self,item_dic):
    with open(self.json_file,'w',encoding='utf-8-sig') as f:
        json.dump(item_dic,f,indent=4,ensure_ascii=False)

def basic_data(self):
    
    item_dic=self.open()

    statusType = "SALE" #상품상태
    saleType = "NEW" #판매유형
    leafCategoryId = self.soup()["category"]["categoryId"] #카테고리넘버
    name = self.soup()["name"] #상품명
    salePrice = self.soup()["salePrice"] #판매가
    stockQuantity = 100 #재고수량
    
    basic_data = {
        "statusType": statusType,
        "saleType": saleType,
        "leafCategoryId": leafCategoryId,
        "name": name,
        "salePrice": salePrice,
        "stockQuantity": stockQuantity,
    }
    try:
        del item_dic["originProduct"]["productLogistics"]
        del item_dic["originProduct"]["saleStartDate"]
        del item_dic["originProduct"]["saleEndDate"]
    except:
        pass
    item_dic["originProduct"].update(basic_data)
    self.save(item_dic)

在 basic_data 函數中，我們創建一個 json 類型並實現一個加載和更新 json 文件的函數。

我想將 def open 函數和 def save 函數合並為一個，以便它們可以運行。

def save_func(self,key,new_data):

## key -> parameter like ["originProduct"] ##

with open(self.json_file,"r",encoding='utf-8-sig') as f:
        item_dic=json.load(f)

item_dic.[key].update(basic_data)

with open(self.json_file,'w',encoding='utf-8-sig') as f:
        json.dump(item_dic,f,indent=4,ensure_ascii=False)

問題是作為key傳遞的參數如果是["originProduct"]是沒有問題的，但是傳遞兩個或者三個的時候，函數內部是否獲取key值就有問題了。

Answer 1

據我所知，您似乎希望根據提供給您的內容重載函數並更新item_dict中的值。 我會警告你，我不習慣在 python 中重載，所以可能有更好的方法來做到這一點。 然而，我制作了一個基於數據更新的腳本作為示例，但我不確定我是否做的比你需要的更多，但我覺得答案就在某處。

main_list = {
    "key1": 43,
    "key2": 54,
    "key3": 95
}


def update(param1, param2 = None):
    if isinstance(param1, dict):  # If parameter 1 is a dictionary, we have our key/data in param1
        update_from_dictionary(param1)
    elif isinstance(param1, list) and isinstance(param2, list):  # If parameter 1 and 2 are both arrays, we were fed keys in param1 and values in param2
        update_values(param1, param2)
    else:  # Assuming that if the above two conditions are not met, we were fed a singular key and value pair
        update_value(param1, param2)


def update_values(keys, values):
    # Handle updating your dictionary object by looping key/value pair using a for loop
    for i in range(0, len(keys)):
        main_list[keys[i]] = values[i]


def update_value(key, value):
    main_list[key] = value


def update_from_dictionary(dictionary):
    for i in dictionary.keys():
        main_list[i] = dictionary[i]


def main():
    print(main_list)
    data = {
        "key1": 1,
        "key2": 2
    }
    update(data)
    print(main_list)


if __name__ == "__main__":
    main()
