Dictionaries for Categorization
Explore how Python dictionaries store data as key-value pairs to organize meals by category and calculate totals. Learn to create a Healthy Meals Dictionary Tracker that groups calories by meal type and apply similar concepts to exercise tracking. Practice coding with AI-generated prompts and gain hands-on experience with dictionaries for effective data management.
The project
You’ve been tracking your meal calories daily, but right now they’re just numbers in a list. Wouldn’t it be more useful if you could organize meals by type? For example, group all breakfasts together, all lunches together, and all dinners together.
Typing just:
Breakfast: 400Lunch: 600Dinner: 300
It's nice, but it doesn’t help you calculate totals for each category. What you need is a dictionary, a structure that stores data as key–value pairs so you can categorize and organize calories by meal type.
Your project: Build a Healthy Meals Dictionary Tracker that groups meals into categories (Breakfast, Lunch, Dinner), calculates totals for each, and shows the overall daily total.
