使用2個關鍵字從json文本中提取正確的ID？

Question

如何正確格式化此代碼以指定正確的顏色和大小時感到困惑。我的目標是獲取顏色Black和尺寸Medium的id。我試圖拉出的輸出是46779。我將如何設置代碼來獲得我期待的輸出？

碼 -

color = "Black" 
size_choice = 'Medium' 

data1 = response1.text 
size_data = json.loads(data1)['styles'] 
for entry in (size_data): 
    if entry['name'] == color['sizes']: 
     if entry['name'] == size_choice: 
      size_id = (entry['id']) 
      print("size id: ", size_id) 

目前的代碼輸出這個錯誤：

if entry['name'] == color['sizes']: 
TypeError: string indices must be integers

Answer 1

的錯誤是在color['sizes']：你聲明color = "Black"，所以你不能查找這樣的密鑰sizes。

您需要添加另一個級別在你遍歷尺寸搜索：

for entry in (size_data): 
    if entry['name'] == color: 
     for size in entry['sizes']: 
      if size['name'] == size_choice: 
       size_id = (size['id']) 
       print("size id: ", size_id) 

>>> size id: 46779
