Exercises

We'll do the first two together, and you'll do the rest on your own.

1. Write a function, named copycat, that simply prints out whatever input it's given.
2. Write a function, named addition, that when given any three numbers, will print out the total sum of all three numbers.
3. Write a function, named conversion, that when given the Fahrenheit temperature, will print out what it is in Celsius. The formula you can use is: C = (F – 32) * 5/9
4. Write a function, named find_the_max, that given any three numbers, will print out the bigger number. Python has the native ability to do this, using the function max(). Do not use it. Instead write this from scratch.
5. For an extra challenge: Given the following data, write a function, named total_students, that calculates how many total students are enrolled in Hogwarts.
   pupils_by_year = [["first years", 40], ["second years", 40], ["third years", 38], ["fourth years", 35], ["fifth years", 30], ["sixth years", 29], ["seventh years", 23]]

Homework

• Keep working on your portfolios and presentations.
• See if you can write yourself any other functions. It'll help you gear up for tomorrow.

In-Class Demos

• Even more web scraping!

Homework

• Prepare your presentation for tomorrow! Send a URL of the project you want to show to [email protected] by tomorrow at 9:30am. Here are some questions to think about:
• General: What did you learn? What can you do now that you could not do 2 weeks ago? What were the biggest challenges/setbacks/frustrations you faced? The biggest surprises/succeses/most awesome things you accomplished?
• Project specific: Tell us what you’re presenting: your portfolio, a dataset you analyzed, a data visualization you created. What are you proud of? What are the next steps you want to take? What are your ultimate goals for the project?
