I've been learning python, and want to get started on my first project, ive finished learning about classes today, and would like to work on my understanding of algorithms, and how everything I've learned can tie together. I'd like to do this because I feel like these online resources give you good Info, but don't teach much about applying these concepts to projects.

I want to make a simple program, where I can type in a recipe name, and print the ingredients, cook time, steps, and name. I'd like to use a list for ingredients, and steps, and I'd like to print those in list format (perhaps wrapped in a border). Is this possible?

Class Recipe:

    def __init__(self, recipe_name, ingredients, cook_time, steps)

        (self.recipe_name = recipe_name)

        (self.ingredients = ingredients)

        (self.cook_time = cook_time)

        (self.steps = steps)



Chicken Noodle = Recipe(Chicken Noodle, [Broth, noodles], 7 minutes, [Bring water to boil, add broth, etc.]

Making a class to contain one recipe makes sense to me, but I would prefer a class to contain all my recipes:

class Recipes:

  def __init__(self):

    self.recipes = {}



  def add_recipes(self, to_add):

      for key in to_add:

          self.recipes[key] = to_add[key]



  def display_recipe(self, name):

    recipe = self.recipes[name]  

    print("Name: ",name)

    print("Ingredients: ", *recipe["ingredients"])

    print("Cook time: ", recipe["cooktime"])



r = Recipes()

r.add_recipes({"Chicken Noodle": {"ingredients": ["Broth", "noodles"], "cooktime": "7 minutes"}})

r.display_recipe("Chicken Noodle")

You have some errors in your code:

Chicken Noodle = Recipe(Chicken Noodle, [Broth, noodles], 7 minutes, [Bring water to boil, add broth, etc.]

Needs to become:

ChickenNoodle = Recipe("Chicken Noodle", ["Broth", "noodles"], "7 minutes", ["Bring water to boil", "add broth, etc."])

The class definition also needs to change a bit, to conform to conventional style and some syntax rules:

class Recipe:

    def __init__ (self, recipe_name, ingredients, cook_time, steps):

        self.recipe_name = recipe_name

        self.ingredients = ingredients

        self.cook_time = cook_time

        self.steps = steps

I think you were pretty close! You don't need those parens in your constructor method. I removed those. To print out the entire recipe, we can simple use the to string function. Change it as you desire:

class Recipe:

    def __init__(self, recipe_name, ingredients, cook_time, steps):

        self.recipe_name = recipe_name

        self.ingredients = ingredients

        self.cook_time = cook_time

        self.steps = steps





    def __str__(self):

      output = ''

      output += 'Here is the recipe for {}:n'.format(self.recipe_name)

      output += 'You will need: {}n'.format(self.ingredients)

      output += 'This recipe takes: {}n'.format(self.cook_time)

      output += 'Here are the steps involved:n'



      for i, step in enumerate(self.steps):

        output += 'Step {}: {}n'.format(i + 1, step)



      return output

You can run this:

chicken_noodle = Recipe('Chicken Noodle', ['Broth', 'noodles'], '7 minutes', ['Bring water to boil', 'add broth'])



print (chicken_noodle)

output:

Here is the recipe for Chicken Noodle:

You will need: ['Broth', 'noodles']

This recipe takes: 7 minutes

Here are the steps involved:

Step 1: Bring water to boil

Step 2: add broth
