Description
因为vs code打开的路径是/User/xxx/19100101/,
当main.py直接读取文件tang300.json的时候，
是默认读取/User/xxx/19100101/tang300.json路径，
而我们的tang300.json实际路径是/User/xxx/19100101/用户名/tang300.json,所以就会报错。
解决方法：vs code ==>文件==>打开（文件）找到/User/xxx/19100101/用户名/，然后打开，再运行main.py就能直接读取tang300.json了。
还有一种教练提供解决方法是：
with open(os.path.join(os.path.dirname(os.path.abspath(__file__)), 'tang300.json')) as f :
这样可以读取到文件的绝对路径

Research direction
Open main.py and inspect how it opens tang300.json; reproduce the failure when running from /User/xxx/19100101/ instead of the user subdirectory. Done means the script can locate tang300.json using the project path handling described in the issue, and the run succeeds from the stated VS Code location.
