 In some cases, you may explicitly revoke access tokens. For example, when an application's user changes the password they use to authenticate to your service. Method `revoke_tokens` invalidates all active access tokens, that were issued to the identity.
 
 ```python
-client.revoke_tokens(identity)
-print("\nSuccessfully revoked all access tokens for identity with ID: " + identity.properties['id'])
+client.revoke_tokens(identity_token_result[0])
+print("\nSuccessfully revoked all access tokens for identity with ID: " + identity)
 ```
 
 ## Delete an identity
 
 Deleting an identity revokes all active access tokens and prevents you from issuing access tokens for the identity. It also removes all the persisted content associated with the identity.
 
 ```python
-client.delete_user(identity)
-print("\nDeleted the identity with ID: " + identity.properties['id'])
+client.delete_user(identity_token_result[0])
+print("\nDeleted the identity with ID: " + identity)
 ```
