在python中保存csv文件，并将datetime作为文件名

import csv
from datetime import datetime

data = [
    {'Name': 'John', 'Age': 28, 'City': 'New York'},
    {'Name': 'Emma', 'Age': 32, 'City': 'London'},
    {'Name': 'Mike', 'Age': 45, 'City': 'Paris'}
]

now = datetime.now()
timestamp = now.strftime("%Y%m%d%H%M%S")

filename = f"data_{timestamp}.csv"

with open(filename, 'w', newline='') as file:
    writer = csv.DictWriter(file, fieldnames=data[0].keys())
    writer.writeheader()
    writer.writerows(data)
