如何使用python在制表符分隔的文件中按行合并字段

import csv

with open('data.txt', 'r') as file:
    # 在这里执行后续操作

    reader = csv.reader(file, delimiter='\t')

    merged_lines = []
    for row in reader:
        merged_line = '\t'.join(row)
        merged_lines.append(merged_line)

    with open('merged_data.txt', 'w') as merged_file:
        merged_file.write('\n'.join(merged_lines))

import csv

with open('data.txt', 'r') as file:
    reader = csv.reader(file, delimiter='\t')
    
    merged_lines = []
    for row in reader:
        merged_line = '\t'.join(row)
        merged_lines.append(merged_line)
    
    with open('merged_data.txt', 'w') as merged_file:
        merged_file.write('\n'.join(merged_lines))
