通过数组将字典写入csv文件，并通过数组插入新行

import csv

data = [
    {'Name': 'John', 'Age': 25, 'City': 'New York'},
    {'Name': 'Jane', 'Age': 30, 'City': 'London'},
    {'Name': 'Bob', 'Age': 35, 'City': 'Paris'}
]

filename = 'data.csv'
fields = ['Name', 'Age', 'City']

with open(filename, 'w', newline='') as csvfile:
    writer = csv.DictWriter(csvfile, fieldnames=fields)
    writer.writeheader()  # 写入列名
    writer.writerows(data)  # 写入数据行

import csv

    {'Name': 'John', 'Age': 25, 'City': 'New York'},
    {'Name': 'Jane', 'Age': 30, 'City': 'London'},
    {'Name': 'Bob', 'Age': 35, 'City': 'Paris'}
]

filename = 'data.csv'
fields = ['Name', 'Age', 'City']
