如何将csv读取到值为列表的字典中-然后将此用于不同的csv文件

import csv

with open('file.csv', 'r') as csv_file:
    csv_reader = csv.DictReader(csv_file)
    data = [row for row in csv_reader]

import csv

def read_csv(file):
    with open(file, 'r') as csv_file:
        csv_reader = csv.DictReader(csv_file)
        data = [row for row in csv_reader]
    return data

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

# 读取CSV文件并创建字典列表
data = read_csv('input.csv')

# 将数据用于不同的CSV文件
write_csv('output.csv', data)
