需要水平合并两个.TXT文件，而空白和结果在终端中不可见

def merge_files(file1, file2, output_file):
    with open(file1, 'r') as f1, open(file2, 'r') as f2, open(output_file, 'w') as output:
        lines1 = f1.readlines()
        lines2 = f2.readlines()
        max_lines = max(len(lines1), len(lines2))

        for i in range(max_lines):
            line1 = lines1[i].strip() if i < len(lines1) else ''
            line2 = lines2[i].strip() if i < len(lines2) else ''
            merged_line = line1 + line2
            output.write(merged_line + '\n')

    print("文件合并完成！")

# 使用示例
file1 = 'file1.txt'
file2 = 'file2.txt'
output_file = 'merged.txt'
merge_files(file1, file2, output_file)
