1. Getting Started

Lecture notes

• Introduction to LAC
• Why learn Python?
• Variables and strings (PCC Chapter 2)

Getting Started

• Try out Google Colab [oratory]
• This sets up a small virtual environment for you on the cloud
• Pros:
  • Uniform environment for everyone
  • Good to interweave text and code
  • Powerful backend, with possibility to expand
• Cons:
  • Must have internet connectivity
  • Tied to Google, encourages dependence
  • Periodically resets
  • Slightly different experience to using an interpreter or saving a program in a file

Practical work

• Open the Colab page for lecture 1

How we will proceed

10+ weeks is not very long, so we need to use our time wisely. I want you to spend as much time coding as possible!

1. First read the assigned chapter of the text book
   • It is good to have a python environment open with you as you read, and try the code
   This should take about 30 minutes to read and test the code
2. Try the problems labelled Before class before class
   This should take about 30 minutes: if it takes much longer let me know
3. We start each class with you asking me questions about the readings, and showing me your code.
4. We then go through the Practical work together
5. When appropriate we talk about assignments

I am also available for individual consultation, email me!

Summary

• We set up a Python environment
• We learned how to work with variables: how to use descriptive variable names and resolve name errors and syntax errors when they arise.
• We learned what strings are and ways to change them
• We learned about fstrings and whitespace
• We started working with integers and floats, and learned some of the ways you can work with numerical data.
• We learned about using comments to make your code easier for you and others to read.
• We read about the philosophy of keeping your code as simple as possible, whenever possible.
