+Examples

+
+Get the list of protected environments for a project::
+
+    p_environments = project.protected_environments.list()
+
+Get a single protected environment::
+
+    p_environments = project.protected_environments.get('production')
+
+Protect an existing environment::
+
+    p_environment = project.protected_environments.create(
+        {
+            'name': 'production',
+            'deploy_access_levels': [
+                {'access_level': 40}
+            ],
+        }
+    )

+Unprotect a protected environment::
