write 2.7 python program,include those *

Create a Python module with a main (in other words, create a runnable Python script), and at least 60 lines of code. Define at least 1 class, and at least 1 function for each class you have defined. Your_main_ should instantiate objects of the classes you have designed, and use them to Use list comprehensions to create lists Use dictionary comprehensions to create dictionaries Use at least 1 decision-making statement (if-elif) invoke the methods defined in those classes *Use at least 1 looping statement (for or while) Use at least I try-except to catch some exceptions. Use the raw-input() function, or command-line arguments, to get some user input Produce some, hopefully interesting, output Add comments to make your script easy to understand (not counted toward the 60-line requirement) Be creative, and make sure it runs
