用两个文件的内容替换文件的一行

def replace_line_with_files(original_file, replace_file1, replace_file2):
    # 读取原始文件内容
    with open(original_file, 'r') as file:
        lines = file.readlines()

    # 读取两个替换文件的内容
    with open(replace_file1, 'r') as file1:
        replace_content1 = file1.read()

    with open(replace_file2, 'r') as file2:
        replace_content2 = file2.read()

    # 找到要替换的行，并将其内容替换为第一个文件的内容
    for i, line in enumerate(lines):
        if '要替换的行' in line:  # 替换条件可以根据实际情况修改
            lines[i] = replace_content1

    # 将更新后的内容写回原始文件
    with open(original_file, 'w') as file:
        file.writelines(lines)

# 示例用法
replace_line_with_files('original.txt', 'replace1.txt', 'replace2.txt')
