I recently spotted an extraneous space after a dot in a bit of my Python code. Obviously invalid syntax apart from the fact that it isn't. This:

name = "Chris"
print(name. upper())

actually works! Why? How? Can anyone explain? It also works with a space before the dot.

Quadratic Functions in Python part 1: Areas of Squares
The word quadratic derives from the Latin quadratus meaning square and in its simplest form a quadratic function calculates the areas of squares from the length of a side.

The Soundex Algorithm in Python
This algorithm assigns identical codes to words or names which it thinks are pronounced the same. It's not brilliant but coding it in Python is an interesting project.

The Soundex Algorithm in Python
Soundex is one of a number of phonetic algorithms which assign values to words or names so that they can be compared for similarity of pronounciation.
