You have to read the file recipes_data.json and load its content into a list of dictionaries.

Expected output format:

[{...}, {...}, {...}]

Usage

Here is a possible test.py to test your functions:

import read_recipes

if __name__ == '__main__':
    print(read_recipes.get_recipes('recipes_data.json'))

$ python test.py
[{'title': 'Vegetable Lasagna', 'ingredients': ['1 lb. lasagna noodles', '1 onion, diced', '2 cloves of garlic, minced', '2 bell peppers, diced', '1 zucchini, diced', '1 eggplant, diced', '1 (28 oz) can crushed tomatoes', '1/4 cup chopped fresh basil', '1/4 cup chopped fresh parsley', '1/4 cup grated Parmesan cheese', '1 cup ricotta cheese', '2 cups shredded mozzarella cheese'], 'people': 6}, {'title': 'Stir-Fried Shrimp with Vegetables', 'ingredients': ['1 lb. large shrimp, peeled and deveined', '2 tbsp. vegetable oil', '1 red bell pepper, sliced', '1 onion, sliced', '1 cup sliced mushrooms', '2 cloves of garlic, minced', '1/4 cup soy sauce', '1/4 cup hoisin sauce', '2 tbsp. rice vinegar', '1 tsp. sesame oil', '1 tsp. sugar', '1/4 tsp. red pepper flakes'], 'people': 4}, {'title': 'Spicy Chicken Tacos', 'ingredients': ['1 lb. boneless, skinless chicken breasts', '1 tbsp. chili powder', '1 tsp. cumin', '1/2 tsp. paprika', '1/4 tsp. salt', '1/4 tsp. black pepper', '1 tbsp. vegetable oil', '8 small flour or corn tortillas', '1 cup shredded lettuce', '1/2 cup diced tomatoes', '1/4 cup sour cream', '1/4 cup chopped fresh cilantro'], 'people': 4}]
