比较两个csv文件并输出第三个csv文件

import csv

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

        for row1, row2 in zip(reader1, reader2):
            compared_row = []
            for value1, value2 in zip(row1, row2):
                # 比较两个值，可以根据实际需求进行修改
                if value1 == value2:
                    compared_row.append(value1)
                else:
                    compared_row.append('Different')

            writer.writerow(compared_row)

# 示例用法
compare_csv('file1.csv', 'file2.csv', 'output.csv')
