Tasks

L1. Zoom

You should install the Zoom app on your computer and set it up to be able to get hands-on, interactive help during office hours.

L1a. Install Zoom

Download Zoom to your computer and install it (you want "Zoom Client for Meetings").

L1b. Turn on screen-sharing (Mac users only)

Follow these instructions to get your camera, your microphone, and (important) screen sharing enabled.

These instructions assume that you know how to get to macOS System Preferences. The following screenshots show you how to get there.

After clicking on "Security and Privacy", click on the "Privacy" tab on the top to get to where the Zoom website instructions begin.

L2. Python

In this class, we are using the Python 3.13 programming language. It is important that you follow these directions to make sure that everyone has the right version installed. Here are instructions for both Mac and Windows users.

L2a. Install Python (macOS)

1. Download Python 3.13 from python.org.
2. Open the downloaded file called python-3.13.1-macos11.pkg (you might not see the .pkg part and that's ok). The file should be in your Downloads folder.
3. Click the Continue buttons several times.

   

   

   

   

   

4. You should now need to enter your password and Python will install (might take a minute). Afterwards, close and delete the installer.
5. Now check to make sure it installed correctly. Open Terminal (you can find the app by going to the Applications/Utilities folder in Finder or by searching for it using Spotlight (press Cmd+spacebar, type Terminal, then press Enter)).
6. Type python3 --version and hit Enter. It should return Python 3.13.1, which means it worked!

L2b. Install Python (Windows)

1. Download Python 3.13 (x86-64) from python.org then and run the installer file called python-3.13.1-amd64.exe.
2. When the installation window pops up, check last box: "Add Python 3.13 to PATH".

   

3. Click "Install Now" at the top.
4. Press WinKey+R to open the Run box.
5. Type cmd then press Enter.
6. Type py --version, then press Enter. It should print Python 3.13.1, which means it worked!

L3. Microsoft Visual Studio Code

I recommend using the same text editor to write your code for labs and projects as I use in class, which is called Microsoft Visual Studio Code (VS Code for short). Here are instructions how to install it for Mac and Windows PC users.

L3a. Install VS Code (macOS)

1. Download Microsoft VS Code.
2. You should see a file with a blue icon called Visual Studio Code in your Downloads folder. Drag it into your Applications folder:

   

3. Open VS Code and create a new file (e.g. press Cmd+N followed by Cmd+S, navigate to your Desktop, then name the new file test.py). You should see a pop-up asking you about installing a Python extension. Click Install:

   

4. VS Code should install it, then you should see a screen like the following. On the lower-right, click the text that says "Python", followed by some numbers:

   

5. A drop-down menu should appear with some options at the top. Click the entry that says Python 3.13.1 64 bit followed by /usr/local/bin/python3:

   

L3c. Install VS Code (Windows)

1. Download Microsoft VS Code and double-click the installer file to install it on your computer.
2. Now let's integrate Python with your code editor VS Code. Open VS Code and create a new file (Press Control+N followed by Control+S. Navigate to your Desktop. Save the file as test.py).
3. You should now see a pop-up in VS Code about a Python extension being recommended. Click Install.

   

4. You should now see "Python 3.13.1" in the bottom right corner of the editor, which means you are all ready to go!

   

L3c. Disable Co-pilot (both)

1. Next, you should disable co-pilot. Using co-pilot in this class is considered academic dishonesty. First click the arrow next to the copilot icon.

   

2. Then, click on "Hide AI Features" in the drop down menu.

   

3. MAC: Click on "Hide AI Features" again in the pop-up.

   

4. WINDOWS: Click on "Hide AI Features" again in the pop-up.

   

5. You should now be all ready to write Python code in VS Code!

L4. Show file extensions

To make sure that you can visually recognize code files, let's make sure that you can see file extensions (like .docx for MS Word files) on your computer.

L4a. Show file extensions (macOS)

1. Go to Finder preferences by click on your desktop background, click Finder on top left corner of the screen then click Preferences....
2. Click Advanced.
3. Make sure Show all filename extensions is checked.

L4b. Show file extensions (Windows)

1. Open up Windows Explorer (e.g. Press Control+N after clicking on your Desktop background).
2. Go to Folder Options:

   

3. Click on the View tab and make sure that Hide extensions for known file types is unchecked.
