مشکلات در list ,int برای پیاده سازی فلوچارت ارایه شده
سلام برای نوشتن کد برای فلوچارت ارایه شده در شکل ضمیمه کد زیر https://i.stack.imgur.com/6a0Li.jpg را نوشته ام که با مشکل O[i]=min(IL[int(prec[i])],temp) TypeError: 'int' object is not subscriptableمواجه شدم. لطف میکنید راهنمایی کنید چگونه مشکلشو حل کنم:
