Today we finished our adventure game. Here is the source for it.

#This is my adventure game

We also took a look at Snap which is an extended re-implementation of Scratch that allows us to build our own blocks. Snap is available at http://snap.berkeley.edu/. We compared our Python code to a similar Snap script.

We compared Python functions to Scratch blocks and made a few blocks of our own using Snap. Here are my slides from today. python session5

This week we looked at creating a game from the beginning and at the steps we might go through to complete it. We looked at flowcharts and pseudocode and then we broke down the program into bite size pieces and wrote functions for these. We got about half way through this and hopefully we’ll complete it next week. Here is a screenshot of what we have completed so far.
