Exercise $1$: $(50$ points$)$ Meal and Nutrition Tracker

Objective: Develop code that allows users to log daily food intake, track nutritional values, and monitor their diet against personal health goals, supporting informed food choices and dietary objectives.

Classes and Components:

Fooditem

Variables: name $($private$),$ calories $($private$),$ proteins $($private$),$ carbs $($private$),$ fats $($private$)$ Instance Methods:

$($self$,$ name, calories, proteins, carbs, fade: Constructor to initialize a new food item with nutritional info.

Getter Methods for each private variable and a display method to print the food item.

$2.$ DailyLog

Variables: date $($private$),$ food$\_$items $($a list of Fooditem instances, private$)$ Instance Methods:

$($self$,$ date$)$: Constructor to initialize a new daily log$.$ add$\_$food$\_$item: Adds a Fooditem instance to the log$.$

get$\_$total$\_$calories: Calculates total calories consumed on that day.

get$\_$total$\_$nutrients: Calculates total proteins, carbs, and fats consumed.

display: Print the daily log$.$

$3.$ NutritionProfile

Variables: user$\_$id $($private$),$ daily$\_$logs $($a dictionary with dates as keys and DailyLog instances as values$)$ Instance Methods:

$($self$,$ user$\_$id$)$: Constructor to initialize a new nutrition profile.

add$\_$daily$\_$log$($self$,$ daily$\_$log$)$: Adds a DailyLog instance to the profile.

get$\_$log$\_$by$\_$date$($self$,$ date$)$: Retrieves a DailyLog by date.

display: Print the nutrition profile.

$4.$ Testing:

Example:

# Create some food items

apple $=$ FoodItem$("$Apple$",95,0\mathrm{.}5,25,0\mathrm{.}3)$

banana $=$ FoodItem$("$Banana$",105,1\mathrm{.}3,27,0\mathrm{.}3)$

# Create a daily $log$ and add food items

daily$\_$log $=$ DailyLog $("2023-04-02")$

daily$\_$log$.$add$\_$food$\_$item$($apple$)$

daily$\_$log$.$add$\_$food$\_$item$($banana$)$Exercise $2$: $(50$ points$)$ Create a moduleObjective: Save the classes Fooditem, DailyLog, and NutritionProfile into a Python file named nutrition$\_$tracker.py$.$ This file will act as your module and import it to another jupyter notebook to produce the same output as in Exercise $1.$

Exercise $3$: $(10$ points$)$ BONUS $-$ Plot the daily log

Explore the package matplotlib and create a bar plot from the daily log$.$ Implement the plot as another method, example: daily$\_$log$.$plot$\_$nutrients$()$ Example:
