从.txt抓取随机行，然后删除该行

import random

def delete_random_line(file_path):
    with open(file_path, 'r') as file:
        lines = file.readlines()

    if lines:
        random_index = random.randint(0, len(lines) - 1)
        line_to_delete = lines[random_index]
        lines.remove(line_to_delete)

        with open(file_path, 'w') as file:
            file.writelines(lines)

        print(f"已删除随机行: {line_to_delete}")
    else:
        print("文件为空，无法删除随机行。")

# 调用示例
delete_random_line('example.txt')
