Homework 2c — Decomposition

1. Barcodes

For this problem, Bit wants to finish the barcodes. There are two starting worlds:

The first row has some blue squares

The finishing worlds should look like this:

The blue squares are turned to blue columns

The starter code is in barcodes.py.

2. Soccer fields

For this problem, Bit wants to plant grass in the soccer fields. There are two starting worlds:

Three rectangular soccer fields

Four rectangular soccer fields

Bit’s job is to put green inside each soccer field:

Soccer fields filled with grass

The starter code is in soccer_fields.py.

3. Bit-a-thon

Bit is participating in a triathlon! Help Bit climb down a mountain, swim across the river, and then cycle to the finish line. There are two race courses:

a mountain going down, then a river, then a flat street

Bit should finish the course, tracing the running path in green and the cycling path in red:

a path following the mountain down and the street to the right

The starter code is in bitathon.py.

Intent

The intent of this assignment is for you to decompose complicated problems well. Quality code uses functions to break a problem into pieces. Each function should have a descriptive name that indicates what it does. The quality code guide contains our standards for decomposition.

Not only will decomposition improve the quality of your code, it will make these problems much easier. Break the problem into the largest repeated sections first, like painting one soccer field. Then break that problem into its largest sections, like dropping down, painting one column, and climbing up.
