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-3.13.15-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 3.13.15, 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-3.13.15-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 3.13.15, which means it worked!

L3. Sublime Text

I recommend using the same text editor to write your code for labs and projects as I use in class, which is called Sublime Text. Here are instructions how to install it for Mac and Windows PC users.

L3a. Install Sublime Text (macOS)

1. Download Sublime Text.
2. Unzip the file you downloaded by double clicking on it.

   

3. You should see a file with a grey and orange called Sublime Text in your Downloads folder. Drag it into your Applications folder:

   

4. Open the program. You will be asked if you are sure. Click "Open".

   

L3c. Install Sublime Text (Windows)

1. Download Sublime Text and double-click the installer file to install it on your computer.
2. Open the installer. You will be asked if you want to allow this app to make changes to your device. Click "Yes".

   

3. When prompted to select destination location. Click "Next >".

   

4. When prompted to select additional tasks, you can optionally check "Add to explorer context menu", this allows you do open an entire folder instead of just one file. It is recommended but not required. Then click "Next >".

   

5. When prompted "Ready to Install", click "Install".

   

6. When the install is complete, click "Finish".
