This is a step by step example of how to read a JSON file in a Python program,
Step 1:Make sure you import JSON module,
import json
Step 2:
Now lets read from an external JSON file,
json_file = open("sample-json-file.txt", "r")
Step 3:
Now we need to convert this json_file object to a String,
json_str = json_file.read()
Step 4:
Now lets convert this json_str to an JSON object,
json_obj = json.loads(json_str)
Step 5:
In this example, we will just iterate the array in the JSON file,
for element in json_obj:
print(element['name'])
print(element['age'])
print(element['city'])
print("-----------")
Complete Program:

json_str = json_file.read()
json_obj = json.loads(json_str)
for element in json_obj:
print(element['name'])
print(element['age'])
print(element['city'])
print("-----------")
