python - 如何将嵌套字典写入 CSV 文件？

Question

我正在尝试将嵌套字典写入 CSV 文件并遇到问题；该文件没有写入任何内容，或者它出错了。

字典看起来像这样：

finalDict = 'How would you rate the quality of the product?': [{'10942625544': 'High '
                                                                    'quality'},
                                                    {'10942625600': 'Neither '
                                                                    'high nor '
                                                                    'low '
                                                                    'quality'},

我已经尝试过将嵌套字典写入 CSV，但我正在努力使其适应我的具体情况。

我的代码目前看起来像：

def writeToCsv(finalDict):
    csv_columns = ['Question', 'UserID', 'Answer']
    filename = "output.csv"
    with open(filename, "w") as filename:
        w = csv.DictWriter(filename, fieldnames=csv_columns)
        w.writeheader()
        for data in finalDict: #where I'm stuck

任何建议将不胜感激！

for question, data in finalDict.items():
   for resp in data:
       row = {'Question': question,
              'UserID': list(resp.keys())[0],
              'Answer': list(resp.values())[0]}
       w.writerow(row)
