我有一个json文件，已使用通过stackoverflow找到的示例进行了部分扁平化。但是，我似乎仍然没有完全扁平化的JSON，因此无法提取到CSV中。我在这里粘贴我的完整代码以及错误。任何帮助将不胜感激！
postcodes = ['P5N2J1', 'P5N2J2','P5N2J3']
response = []
for postcode in postcodes:
rr = requests.get('https://represent.opennorth.ca/postcodes/{}'.format(postcode))
data = json.loads(rr.text)
response.append(data)
#print(response)
x = response
def flatten(items):
non_list_items = []
for item in items:
if isinstance(item, list):
for inner_item in flatten(item):
yield inner_item
else:
non_list_items.append(item)
yield non_list_items
flatten(x)
x

答案 0 :(得分：0)
由于x["representatives_centriod"]返回list而不是dict，因此可以通过添加嵌套循环来存储数据。此外，"code"包含在x中，而不包含在x["representatives_centriod"]中。因此，您应该在嵌套循环之前存储"code"数据。
例如，
for i in x:
code = i['code']
for j in i['representatives_centroid']:
f.writerow([j['name'], j['elected_office'], j['district_name'], code])
