Python

Notes

The python version we're going to standardize on is Python 2.7 - this is because it's simpler to learn and use than Python 3, and there are a large number of libraries that still do not support Python 3. We'll switch over when all of the major data analysis libraries and Flask switches over to Python 3. Here's some thoughts from the authors of Flask about it.

Pre-work

If you don't have any experience with Python at all, the first place to start is Learn Python The Hard Way.

  • Get comfortable with the syntax of Python with exercises 0 through 39
  • Take a tour of Object Oriented Python with exercise 40, 41, and 42
  • Understand Inheritance with exercise 44[^1].
