Python TypeError
TypeError is another common error that can occur when working with JSON data in Python. This error is raised when there is a mismatch between the expected data type and the actual data type of a certain value in the JSON data.
Problem Statement
In this example, we have created a json_data with the keys name, age then we have used the try-catch block to get the error if it comes otherwise we are printing the sum of the number key which consists of numbers from 1 to 5.
Python3
import json # 5 is in string type json_data = '{ "numbers": [1, 2, 3, 4, "5"] }' data = json.loads(json_data) numbers = data[ "numbers" ] try : total = sum (numbers) print (total) except TypeError: print ( "Mismatch Type Detected" ) |
Output
Mismatch Type Detected
Explanation
In this example, we catch the TypeError exception when any data type other than an integer is identified. To fix this error remove quotations around 5 in the numbers list.
Solution
Python3
import json # 5 is in string type json_data = '{ "numbers": [1, 2, 3, 4, 5] }' data = json.loads(json_data) numbers = data[ "numbers" ] try : total = sum (numbers) print (total) except TypeError: print ( "Mismatch Type Detected" ) |
Output

JSON Parsing Errors in Python
JSON is a widely used format for exchanging data between systems and applications. Python provides built-in support for working with JSON data through its JSON module. However, JSON parsing errors can occur due to various reasons such as incorrect formatting, missing data, or data type mismatches.
There are different JSON parsing errors that can occur depending on the specific scenario when the JSON data is being parsed. Some common JSON parsing errors that occur in Python are:
