如何格式化python中的JSON

Question

create a json file the file should be formatted like this:

 {"name": "YOU", 
    "items": {
    "item 1": "bread", 
        "quantity of item 1": 2, 
        "price of item1": "0.60", 
    "item 2": "milk", 
        "quantity of item 2": 10, 
        "price of item2": "6.00"
    }
}

//I tried to use f.write(

When I tried to create a dictionary and add a the new line operator it would just add \n to the file

order = {"name": name, "items": {}}
a= 1
for i in items:
    
     order["items"].update({f'item {a}': i.item, +'\n' f'quantity of item {a}': i.quantity,+'\n' f'price of item{a}': i.price()})
     a+=1

Python has the json library for formatting dictionaries into json formats:

import json
json_string = json.dumps(items)
print(json_string)

Another issue is that you're defining key-value pairs within a list - you want to use {} instead of [] if you're giving values keys as well, and placing commas in some missed lines:

{
    "name": "name",
    "items": {
        "item name": "item1",
        "quantity": 1,
        "price": 1.00
    }
}
