+### Enable Logging in the SDK
+Python sdk uses the logger *'authorizenet.sdk'*. By default the logger is not configured in the sdk for writing output. If you need logging in the sdk, you should configure the logger in your code according to your need.
+
+A sample logger configuration is given as below:
+
+```python
+	import logging
+	logger = logging.getLogger('authorizenet.sdk')
+	handler = logging.FileHandler('anetSdk.log')  
+	formatter = logging.Formatter('%(asctime)s %(name)-12s %(levelname)-8s %(message)s')
+	handler.setFormatter(formatter)
+	logger.addHandler(handler)
+	logger.setLevel(logging.DEBUG)
+	logger.debug('Logger set up for Authorizenet Python SDK complete')
+``` 
+
