Python调用Proj05Runner模块run方法输出格式异常如何修复

你的问题根源是字符串拼接逻辑错误，每一句版权声明后都拼接了原字符串、子串和截取结果，才导致内容穿插。调整拼接顺序，先完整拼接4行版权声明，再追加业务数据即可，修改后的模块代码如下：

def run(str, subStr):
    """Returns a substring of any given string based upon a given range of characters before and after the substring"""
    str_range = 3
    if subStr in str:
        str_modified = str[str.index(subStr) - str_range : str.index(subStr) + len(subStr) + str_range]
        # 先拼接完整4行版权声明
        copyright_content = (
            "I certify that this program is my own work\n"
            "and is not the work of others. I agree not\n"
            "to share my solution with others.\n"
            "Print your name here."
        )
        # 版权声明后拼接业务数据
        return f"{copyright_content}\n\n{str}\n{subStr}\n{str_modified}"
    else:
        return "ERROR: subStr not found in str!"

修改后运行驱动代码，输出会先展示4行完整的版权声明，再空一行依次输出原字符串、子串、截取结果，符合需求。
