`json.load() vs. json.loads(): When Should I Use Each Method for Reading JSON Data?`

Reading JSON from a File

When handling JSON data, it's crucial to know the distinction between the json.load() and json.loads() methods.

json.load()

The json.load() method is used for directly reading JSON data from a file object. Its usage is straightforward:

import json

with open('strings.json') as f:
    d = json.load(f)

This code successfully reads the JSON file "strings.json" and assigns its content to the d variable. The result can be accessed as a Python dictionary.

json.loads()

In contrast, the json.loads() method is used to read JSON data from a string. It expects a string as an argument and converts it into a Python dictionary.

import json

with open('strings.json') as json_data:
    d = json.loads(json_data)

In this example, you were mistakenly using json.loads() on a file object, which led to the "expected string or buffer" error.

Error with json.loads()

The error you encountered with json.loads() likely indicates an issue with the JSON data itself. Using a JSON validator would be beneficial in identifying and fixing any invalid content.
