Python/Json:Expecting property name enclosed in double quotes

Python/Json: Expecting property name enclosed in double quotes

Have you ever come across the error message "Expecting property name enclosed in double quotes" while working with JSON objects in Python? If so, you're not alone! This error usually occurs when there is an issue with the format of the JSON object.

Let's break down the issue and discuss some easy solutions.

Understanding the Problem

The error message suggests that there is an incorrect format in the JSON object. In JSON, property names must be enclosed in double quotes. However, in the provided example, the property names are enclosed in single quotes, which is not allowed.

The problematic JSON object:

{'http://example.org/about': {'http://purl.org/dc/terms/title': [{'type': 'literal', 'value': "Anna's Homepage"}]}}

Easy Solutions

To fix this issue, we have a couple of solutions:

Solution 1: Change Single Quotes to Double Quotes

One way to resolve this problem is to replace all the single quotes with double quotes in the JSON string. Here's how you can do it in Python:

data = '{"http://example.org/about": {"http://purl.org/dc/terms/title": [{"type": "literal", "value": "Anna\'s Homepage"}]}}'
json.loads(data)

By making this adjustment, the JSON parser will recognize the property names as valid, and the error should no longer occur.

Solution 2: Escape the Single Quotes

If you want to keep the property names enclosed in single quotes for some reason, you can escape the single quotes within the JSON string. Here's an example:

data = "{'http://example.org/about': {'http://purl.org/dc/terms/title': [{'type': 'literal', 'value': \"Anna's Homepage\"}]}}"
json.loads(data.replace("'", "\\'"))

In this solution, we use the replace method to escape the single quotes with backslashes, making them valid within the JSON format.

Choose Your Best Solution

Both solutions will solve the "Expecting property name enclosed in double quotes" error. However, choosing the right solution depends on your specific use case. If you have control over the JSON creation, it's generally recommended to use double quotes for property names to ensure compatibility and adhere to the JSON specification.
