Tutorials/Python 3: Making the Leap!
On Wednesday at 10:40 in the Robert Street Lecture Theatre I will be running a tutorial on porting code written for python 2 to work in python 3.
This session will be live and interactive, so to get the most out of the tutorial, please bring along a laptop and be ready to hack.
What will be covered?
Getting code to run on python 3 is a *massive* topic, and we could spend an entire week looking at it and not cover everything. As we only have 100 minutes we will only cover a relatively small, but IMHO important, subset of the topic. In particular, we will look at.
- How to get code which currently runs under 2.7 to run under 3.3 (without maintaining 2.7 backwards compatibility).
- How to modify your 2.7 code to be as close to 3.3 compatible as possible.
- How to use different tools to automate the porting process.
- Common gotchas with the automated tools which may require manual intervention
- Strategies for using all the different tools and techniques to make the porting process as simple as possible.
We unfortunately won't be able to cover some interesting topics, including
- How to get code to run under python 2 and 3 simultaneously.
- How to port python extension modules.
- How to use brand new features which have been introduced in python 3.
The session will cater to a fairly broad range of abilities. If you're a python newbie, you should be able to keep up with everything. If you're a python guru you might just learn something new (I know I did while preparing the session!).
What to bring
- A laptop with python 2 and python 3 installed.
- A shell and text editor.
- Any python code which you'd like help porting form 2 to 3.
- The example code from github: https://github.com/timleslie/LCA_py2to3
All examples are platform agnostic and should work on linux/osx/windows.
What to do
- Turn up :-)
- Follow along with all the examples.
- Try out the techniques on your code as we go.
- Ask questions if you would like clarification...
- ... but understand that the answer might be "that's beyond the scope of this session, come and chat with me later".
I look forward to seeing you all for a fun and interesting session.
