#try是尝试执行某代码如果错则执行except后的代码（except前要写错误类型）
try:
    with open("作品存档1","r") as f:
        c = f.read()
        print(c,"你好呀！")
    #这里报错则说明没有“作品存档1”的文件，也就是说玩家没有输入过要保存的东西
except OSError:
    a = input('输入用户名')
    #新建一个叫“作品存档1”的文本文档
    with open("作品存档1","w") as f:
        f.write(a)    #将输入的字符串写入文件
        print("保存成功！")
    with open("作品存档1","r") as f:
        c = f.read()
        print(c,"你好呀！")
