In-class, doing Exercise 12.3

Write a function called most_frequent that takes a string and prints the letters in decreasing order of frequency. Find text samples from several different languages and see how letter frequency varies between languages. Compare your results with the tables at http://wikipedia.org/ wiki/Letter_frequencies.

Recall the Historgram function from Chapter 9, p.105:

def histogram(s):
	d = dict()
	for c in s:
		if c not in d:
			d[c] = 1
		else:
			d[c] += 1
	return d
