合并csv文件

import csv

# 定义要读取的CSV文件路径列表
csv_files = ['results_01.csv', 
             'results_02.csv', 
             'results_03.csv',
             'results_04.csv',
             'results_05.csv',
             'results_06.csv',
             'results_08.csv',
             'results_10.csv',
             'results_11.csv',
             ]  

# 定义输出文件路径
output_file = 'merged_output.csv'

# 打开输出文件，准备写入
with open(output_file, 'w', newline='', encoding='utf-8') as outfile:
    writer = csv.writer(outfile)
    
    # 遍历每个CSV文件
    for file in csv_files:
        with open(file, 'r', encoding='utf-8') as infile:
            reader = csv.reader(infile)
            
            # 逐行读取当前CSV文件的内容，并写入输出文件
            for row in reader:
                writer.writerow(row)

print(f"所有CSV文件已逐行合并，结果保存在 {output_file} 中")
