+## Exercise: Using RPC in Python
+
+Python provides built-in support for RPC through the [xmlrpc](https://docs.python.org/3/library/xmlrpc.html) module.
+
+1. Try the example in `exercises/python-rpc` with your teammates.
+2. Modify the example to implement RPC services that sends bytes of a file (e.g. `yourimage.jpg`) to the client.
+
+**Hint**:
+
+- Use `open` to open a file and read it in binary mode.
+- Use `xmlrpc.client.Binary` to wrap the bytes.
+- You can find example in the documentation of [xmlrpc](https://docs.python.org/3/library/xmlrpc.html).
