如何将嵌套字典写入CSV文件？

import csv

data = [
    {"Name": "John", "Age": 28, "Country": "USA"},
    {"Name": "Emma", "Age": 32, "Country": "Canada"},
    {"Name": "Sophia", "Age": 25, "Country": "UK"}
]

csv_file = "data.csv"
fields = ["Name", "Age", "Country"]

with open(csv_file, 'w', newline='') as file:
    writer = csv.DictWriter(file, fieldnames=fields)
    writer.writeheader()
    writer.writerows(data)

import csv

data = [
    {"Name": "John", "Age": 28, "Country": "USA"},
    {"Name": "Emma", "Age": 32, "Country": "Canada"},
    {"Name": "Sophia", "Age": 25, "Country": "UK"}
]

csv_file = "data.csv"
fields = ["Name", "Age", "Country"]

with open(csv_file, 'w', newline='') as file:
    writer = csv.DictWriter(file, fieldnames=fields)
    writer.writeheader()
    writer.writerows(data)
