The Python json.__version__ attribute provides the version of the built-in json module.

This attribute helps in checking the version of the json module being used, which can be useful for debugging and compatibility checks.

Syntax

Following is the syntax of the json.__version__ attribute −

import json

version = json.__version__

Return Value

This attribute returns a string representing the version of the json module.

Example: Getting JSON Module Version

In this example, we retrieve and print the version of the json module −

import json

# Get JSON module version
json_version = json.__version__

print("JSON Module Version:", json_version)

Following is the output obtained −

JSON Module Version: 2.0.9

Example: Compatibility with a Minimum Required Version

In this example, we compare the json.__version__ with a required version to ensure compatibility −

import json

# Minimum required version
required_version = "2.0.0"

# Get installed version
installed_version = json.__version__

# Compare versions
if installed_version >= required_version:
   print("Compatible JSON module version:", installed_version)
else:
   print("Update required! Current JSON module version:", installed_version)

Following is the expected output −

Compatible JSON module version: 2.0.9

Example: Logging JSON Module Version

In this example, we log the version of the json module for debugging purposes −

import json
import logging

# Configure logging
logging.basicConfig(level=logging.INFO)

# Get JSON module version
json_version = json.__version__

# Log the version
logging.info(f"Using JSON module version: {json_version}")

Following is the expected output in the log −

INFO:root:Using JSON module version: 2.0.9

Example: Checking JSON Version Before Execution

In this example, we check the JSON module version before executing JSON-related operations −

import json

# Required version for compatibility
required_version = "2.0.9"

# Check JSON module version
if json.__version__ >= required_version:
   print("Compatible JSON version detected:", json.__version__)
else:
   print("Warning: JSON version", json.__version__, "may not be fully compatible.")

Following is the expected output if the version is compatible −

Compatible JSON version detected: 2.0.9
