## Read file
### Instructions
Create a file `read_file.py` which will have a function `get_recipes(file_name)` that takes a file as an argument.
Create another file `recipes_data.json` and copy/paste on it the following content:
```json
[
{
"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
}
]
```
You have to read the file `recipes_data.json` and load its content into a list of dictionaries.
Expected output format:
```python
[{...}, {...}, {...}]
```
### Usage
Here is a possible `test.py` to test your functions:
```python
import read_recipes
if __name__ == '__main__':
print(read_recipes.get_recipes('recipes_data.json'))
```
```bash
$ 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}]
