aListOfWords = ['one','word','or','many']
aListOfCharacters = ['a','s','d','f']

aStringOfCharacters = 'asdf'
aWord = aStringOfCharacters

Now what part do you not understand?

You use a list of words any time you want to process multiple words. 
For example a spelling checker may break a document into a list 
of words and compare each word to a reference list of correctly 
spelled words.

A list of characters is rarely used in Python since you can use 
a string in almost every case. 

You will find some more information in the "Raw Materials" topic 
of my tutorial.
