 Install this package with ``pip install sentry-sdk``. Then, in your code:
 
-    import sentry_sdk
-    sentry_sdk.init(dsn="https://foo@sentry.io/123")
+```python
+import sentry_sdk
+sentry_sdk.init(dsn="https://foo@sentry.io/123")

 After initialization, you can capture exceptions like this:
 
-    sentry_sdk.capture_exception(ValueError())
+```python
+sentry_sdk.capture_exception(ValueError())
 
-    try:
-        raise ValueError()
-    except Exception:
-        sentry_sdk.capture_exception()
+try:
+    raise ValueError()
+except Exception:
+    sentry_sdk.capture_exception()

 ...or send messages:
 
-    sentry_sdk.capture_message("Hi Sentry!")
+```python
+sentry_sdk.capture_message("Hi Sentry!")
+```
 
 ## Scopes (contexts, tags)
 
 You can create a scope to attach data to all events happening inside of it:
 
-    with sentry_sdk.Hub.current.push_scope():
-        with sentry_sdk.configure_scope() as scope:
-            scope.transaction = "my_view_name"
-            scope.set_tag("key", "value")
-            scope.user = {"id": 123}
-
-        # ValueError event will have all that data attached
-        capture_exception(ValueError())
+```python
+with sentry_sdk.Hub.current.push_scope():
+    with sentry_sdk.configure_scope() as scope:
+        scope.transaction = "my_view_name"
+        scope.set_tag("key", "value")
+        scope.user = {"id": 123}

+    # ValueError event will have all that data attached
     capture_exception(ValueError())
 
+# This one not since it is outside of the context manager
+capture_exception(ValueError())

 Scopes can be nested. If you call ``push_scope`` inside of the
 ``with``-statement again, that scope will be pushed onto a stack. It will also
 inherit all data from the outer scope.

 If you never call ``init``, no data will ever get sent to any server. In such
 situations, code like this is essentially deadweight:
 
-    with sentry_sdk.configure_scope() as scope:
-        scope.user = _get_user_data()
+```python
+with sentry_sdk.configure_scope() as scope:
+    scope.user = _get_user_data()
+```
 
 Sentry-Python supports an alternative syntax for configuring a scope that
 solves this problem:
 
-    @sentry_sdk.configure_scope
-    def _(scope):
-        scope.user = _get_user_data()
+```python
+@sentry_sdk.configure_scope
+def _(scope):
+    scope.user = _get_user_data()
+```
 
 Your function will just not be executed if there is no client configured.
 
 In your testing and development environment you still might want to run that
 code without sending any events. In that case, simply call ``init`` without a
 DSN:
 
-    sentry_sdk.init()
+```python
+sentry_sdk.init()
+```

 You can also pass a callback to `add_breadcrumb` like so:
 
-    sentry_sdk.add_breadcrumb(lambda: {

+})
