1. Write a function char_freq() that takes a string and builds a frequency listing of the characters contained in it. Represent the frequency listing as a Python dictionary. Try it with something like char_freq("abbabcbdbabdbdbabababcbcbab").

2. Write a function char_freq_table() that take a file name as argument, builds a frequency listing of the characters contained in the file, and prints a sorted and nicely formatted character frequency table to the screen.

3. The third person singular verb form in English is distinguished by the suffix -s, which is added to the stem of the infinitive form: run -> runs. A simple set of rules can be given as follows:

   a. If the verb ends in y, remove it and add ies b. If the verb ends in o, ch, s, sh, x or z, add es c. By default just add s

Python exercises

1. Define a function max() that takes two numbers as arguments and returns the largest of them. Use the if-then-else construct available in Python. (It is true that Python has the max() function built in, but writing it yourself is nevertheless a good exercise).

2. Define a function max_of_three() that takes three numbers as arguments and returns the largest of them.

3. Define a function that computes the length of a given list or string. (It is true that Python has the len() function built in, but writing it yourself is nevertheless a good exercise).

4. Write a function that takes a character (i.e. a string of length 1) and returns True if it is a vowel, False otherwise.
