If you don't use comprehensions in your daily coding very often, the first thing you should do is search through some existing code and find some for loops. See if any of them can be trivially converted to a generator expression or a list, set, or dictionary comprehension.

Test the claim that list comprehensions are faster than for loops. This can be done with the built-in timeit module. Use the help documentation for the timeit.timeit function to find out how to use it. Basically, write two functions that do the same thing, one using a list comprehension, and one using a for loop. Pass each function into timeit.timeit, and compare the results. If you're feeling adventurous, compare generators and generator expressions as well. Testing ...
