  Each day I will post the lecture videos, homework, reading, and other information. Make sure to check here for each day of class.
  • Day 1 - Tuesday - 9/1 - Click Here
    
    PRE-CLASS:

    Most days there will be videos, homework assignments, and reading that you are expected to complete before class. It is okay if you don't get all the homework done, but you should attempt every part and keep trying until you are completely stuck and have questions to bring to class.

    CLASS TIME:

    Notes - Computer Setup - Review
    Slides - Computer Setup - Review
    Video - Set up your computer and be successful in this class (important that this is done this week!)
    Send me your GitHub username - I need this to set up your sandbox and your team's repository. Type just the username, not the whole web address.
    
    Once your two repos are set up (see today's Computer Setup notes and the Git Command Card at the top of this page), HW_day1.ipynb will be in your sandbox - we will work on this in class.
    
    Reading: Python for Data Analysis
    Chapters 2.3 and all of Chapter 3 of our book are a good review of python basics. Please glance through these chapters before starting your prep for Day 2! We will be working a lot in Pandas, but it is important that you know how to deal with Python lists, dictionaries, sets, and tuples (p.47-64). It is helpful to learn how to do list comprehensions p.64, but as long as you can do a for loop you will be fine. We will make use of functions and lambdas as a way to organize our code p.65-76. We will practice at reading in different data types (mostly with pandas but sometimes with other methods) p.79-80.
    

    ANNOUNCEMENTS:

    Finish HW_day1.ipynb with your team - reach out if you need help!
    Video - Github Team Workflow (recorded for the old one-repo setup. Follow the Git Command Card instead.)
    Start Prepping for Day 2 - click on the Day 2 link and complete the PRE-CLASS materials.

    
    
  • Day 2 - Thursday - 9/3 - Click Here
    
    PRE-CLASS:

    Reading: Python for Data Analysis: Chapter 5
    NOTE: The book is a great reference for general data analysis. Don't feel like you have to read it line by line. The lecture notes will follow somewhat closely to the book. Have a Jupyter Notebook open so you can try some of the commands!
    
    Notes - Pandas
    Slides - Pandas - summary of functions
    Video - Pandas Review-Advanced
    Pull the latest into your sandbox (git fetch upstream, then git merge upstream/main), then make sure HW_day2.ipynb is there - we will work on this in class.
    
    Push your team's work to your team repo before class starts - this shows your attempt and a timestamp on your progress.

    CLASS TIME:

    Pandas!
    Work on finishing up HW_day1.ipynb.
    Go through warm-up you try problems.
    Work on Titanic Data.
