从输入文件中获取特定的行值，并将其写出到新的.csv文件

import csv

def get_specific_lines(input_file, output_file, line_numbers):
    with open(input_file, 'r') as file:
        lines = file.readlines()

    specific_lines = [lines[line_number-1] for line_number in line_numbers]

    with open(output_file, 'w', newline='') as file:
        writer = csv.writer(file)
        writer.writerows([line.strip().split(',') for line in specific_lines])

# 示例调用
input_file = 'input.txt'
output_file = 'output.csv'
line_numbers = [2, 4, 6]  # 假设要获取第2、4、6行的值

get_specific_lines(input_file, output_file, line_numbers)
