Now it's time to extend our previous problem - Food Diary

We are going to have a file, called calories.json, where we are going to have calories information for different foods.

The file is going to have the following structure:

{
  "pizza": 100,
  "broccoli": 100
}

We keep calories per 100g of the given food.

Now, when we add a food into our diary, we are going to provide more information:

• The amount (either in g or kg) of what we have eaten

Now, using the calories.json we can calculate how much calories have we taken with that food.

For example:

Enter command> meal pizza
How much have you eaten?> 500g
Ok, this is a total of 500 calories for this meal.

OR

Enter command> meal broccoli
How much have you eaten?> 2kg
OK, this is a total of 200000 calories for this meal.

Now, if you have eaten something that is not located in the calories.json database, have the program ask you for the calories of that food for 100g.

After this, update the calories.json database.

For example

$ cat calories.json
{
  "pizza": 100,
  "broccoli": 100
}
$ python3 food.py
Enter command> meal icecream
How much have you eaten?> 100g
I don't have icecream in the calories database.
How much calories per 100g?> 100
OK, this is a total of 100 calories for this meal.
Enter command>goodye
Goodbye!
$ cat calories.json
{
  "pizza": 100,
  "broccoli": 100,
  "calories": 100
}

Now, we are going to remove the free file structure from the previous problem and start saving our diary in a CSV file!

Figure out the columns.
