一种将两个文本文件的内容合并为一个文本文件的方法，该方法使用分隔符来区分内容来自两个不同的文件

def merge_files(file1, file2, output_file, delimiter):
    with open(file1, 'r') as f1, open(file2, 'r') as f2, open(output_file, 'w') as output:
        content1 = f1.read()
        content2 = f2.read()
        merged_content = content1 + delimiter + content2
        output.write(merged_content)

# 使用示例
file1 = 'file1.txt'
file2 = 'file2.txt'
output_file = 'merged_file.txt'
delimiter = '---'  # 分隔符可以根据需要自行定义
merge_files(file1, file2, output_file, delimiter)
