Issues iterating via and accessing JSON parts with Python

When you get this error whereas making an attempt to entry information in a JSON object verify to see whether or not you are attempting to entry an inventory or a dict (dictionary).

Python lists appear to be this:

mylist = [“apple”, “banana”, “cherry”]

Python record:

A python dict seems to be like this:

automobile = {
"model": "Ford",
"mannequin": "Mustang",
"12 months": "1964"
}

When you’ve got a json object like this with an inventory of automobiles and the attributes of every automobile are saved as a dict:

automobiles:
[{
"brand": "Ford",
"model": "Mustang",
"year": "1964"
},
{
"brand": "Jeep",
"model": "Gladiator",
"year": "2022"
}
]

In case you are accessing an inventory, loop via the objects within the record:

for merchandise in json:
#do one thing

When you’ve got a dict you’ll be able to entry the attribute you need utilizing brackets:

merchandise['name']

When you get the error:

TypeError: record indices have to be integers or slices, not str

then you might be in all probability making an attempt to entry a component in a dict, however first you must iterate via your record.

So as an alternative of this:

automobiles.model

Do that:

for automobile in automobiles:
print (automobile['Brand'])
