About
Every day, people face a lot of difficult choices: for example, what to prepare for breakfast, lunch, and dinner? Are the necessary ingredients in stock? With the Meal Planner, this can be quick and painless! You can make a database of categorized meals and set the menu for the week. This app will also help create and store shopping lists based on the meals so that no ingredient is missing.
Training project
This project allows you to practice and strengthen your coding skills, helping you get ready for more advanced tasks ahead.
What you'll learn
Once you choose a project, we'll provide you with a study plan that includes all the necessary topics from your course to get it built. Here’s what awaits you:
Write a program that saves a meal with its properties — category, name, necessary ingredients — and prints them in a proper format.
Create a menu that allows you to add new meals, show them, and quit the program.
Improve your program so that it stores all the meals in the database and allows you to access them even after you close and reopen the app.
Work on the “show” command: add the ability to display the meals by the chosen category.
It’s time to plan meals for the whole week! With the new "plan" command, your app should be able to help the user plan their daily meals based on the saved options.
Finally, your app should generate a shopping list containing all the required ingredients for the planned meals and save this list to the file together with the weekly plan.
