We'll run both together in one file called `udp.py` instead of running them separately. We've written some python code in the main function that allows you to specify which function you want the code to run, the `server` or the `client`.

To run the code, you would need to follow these steps:


1. Type your code and when you are ready to run the program, click on **Run**. The server code should start up automatically.
2. Open another terminal by clicking on **+**
3. Type the command `python3 /usercode/udp.py client` Note that it can be `server` in place of `client`.
4. Enter the text in the client window and see the effect.
5. If the program is not running to your satisfaction:
    1. Kill the running server program by typing the break sequence `ctrl+c` or `command+c` in both of the terminal windows.
    2. Change the code
    3. Click on **Run**. 
    4. Type command `python3 /usercode/udp.py server` and `python3 /usercode/udp.py client` in the first and second terminal window, respectively. Go back to step 4.

> Every time you make a change to the code you must click **run** for the changes to take effect.

We've spent the last few lessons writing code for a very basic client and a server. Let's see these in action in this lesson!
