The readability of code and make it consistent across the wide The guidelines provided here are intended to improve One of Guido’s key insights is that code is read much more often than A Foolish Consistency is the Hobgoblin of Little Minds In the event of anyĬonflicts, such project-specific guides take precedence for that project. Many projects have their own coding style guidelines. Identified and past conventions are rendered obsolete by changes in This style guide evolves over time as additional conventions are Guido’s original Python Style Guide essay, with some additions from This document and PEP 257 (Docstring Conventions) were adapted from Please see theĬompanion informational PEP describing style guidelines for the C code The standard library in the main Python distribution.

Instead of drawing thick lines with I decided to draw rectangles thinly with. This method returns the index of the first rectangle in the list where a collision was detected, otherwise -1. In my solution, I choose to move the rectangle by 1 to one side and check that the rectangle does not collide with any of the adjacent rectangles. Therefore, a rectangle must be modified, it can either be inflated on one side or moved to one side. Since the rectangles do not overlap, they do not collide and a collision check fails. Iterate through all rectangles and create a list of adjacent rectangles: for i, r in enumerate(rectangles): Basically, for each side of a rectangle, you need to check if it is docked to another rectangle in the list, and draw a line segment along that side if it is not docked.
