我需要关于如何将字典元素保存到csv文件中的帮助

import csv

data = {'Name': 'John', 'Age': 30, 'City': 'New York'}

filename = 'data.csv'
with open(filename, 'w', newline='') as csvfile:
    writer = csv.DictWriter(csvfile, fieldnames=data.keys())

    writer.writeheader()

    writer.writerow(data)

import csv

data = {'Name': 'John', 'Age': 30, 'City': 'New York'}
filename = 'data.csv'

with open(filename, 'w', newline='') as csvfile:
    writer = csv.DictWriter(csvfile, fieldnames=data.keys())
    writer.writeheader()
    writer.writerow(data)
