Python JSON load file

Use json.loads() method to load JSON files in Python. This method returns a dictionary. json.load() accepts file object, parses the JSON data, and populates a Python dictionary.

json.load(file object)

Python JSON load file

Simple example code read the content of this file. Below is the implementation.

You need to import the module before you can use it.

data.json

{
  "emp": [
    {
      "name": "John",
      "subject": "Data structures",
      "Articles": 2
    },
    {
      "name": "Mike",
      "subject": "Algorithms",
      "Articles": 10
    },
    {
      "name": "Rohit",
      "subject": "NAN",
      "Articles": 8
    }
  ]
}

main.py

import json

# Opening JSON file
f = open('modules/data.json')

# returns JSON object as a dictionary
data = json.load(f)

# Iterating through the json list
for i in data['emp']:
    print(i)

# Closing file
f.close()

Output:

Suppose, you have a file named person.json that contains a JSON object.

{"name": "Bob", 
"languages": ["English", "French"]
}

Here’s how you can parse this file:

import json

with open('path_to_file/person.json', 'r') as f:
  data = json.load(f)

# Output: {'name': 'Bob', 'languages': ['English', 'French']}
print(data)
