python读写文本，将信息保存至文件中并读取出来

请编写一个存储玩家资料的程序。程序要求输入玩家的姓名、年龄、国籍。要求使用字典存储玩家资料，且要求程序输入玩家信息后，可以在退出程序前将玩家信息存储到一个与Python程序同目录名字为player. txt的文本文件中，并将txt文件中的用户信息读取到屏幕上，可以选择使用readline()方法读取信息，即每次读取一名玩家的信息。读取到的信息内容是一行字符串，该字符串以”\n”结尾。首先需要使用字符串函将”\n”去掉，去掉”\n”后的玩家的各种信息之间是以空格为区分的。可以使用split()函数将玩家信息按顺序存储在一个列表中。最后通过挨个读取列表项的方式将玩家信息逐一读取到屏幕上

该回答引用chatgpt:

def save_player_info(player_info):
    with open("player.txt", "a") as file:
        file.write(player_info + "\n")
