Python :如何比较两个csv文件并在新文件中打印出匹配的字符串

import csv

def compare_csv(file1, file2, output_file):
    with open(file1, 'r') as f1, open(file2, 'r') as f2, open(output_file, 'w') as output:
        reader1 = csv.reader(f1)
        reader2 = csv.reader(f2)
        writer = csv.writer(output)

        # 读取文件1的内容并存储在列表中
        file1_data = list(reader1)

        # 遍历文件2的每一行
        for row2 in reader2:
            # 遍历文件1的每一行
            for row1 in file1_data:
                # 比较两行数据是否匹配
                if row2 == row1:
                    # 将匹配的行写入新文件
                    writer.writerow(row2)
                    break

# 调用函数进行比较
compare_csv('file1.csv', 'file2.csv', 'output.csv')
