Problems

Problem 0: 50 points

Modify your program from problem 2.1 so that users can add their own sounds. Call it customFX.py.

  1. Instead of a big if statement, use a dictionary to store the sounds.
  2. The user should type new [name] [sound] if they want to make a new sound. See interaction below for example.

Hint: You can use the split method on the user input to break it into the first part and the second part. You can then use len to see if the user included a number of times. You can do this instead of the finding and slicing that you did in homework 2.

Hint: Make sure to initialize your dictionary OUTSIDE of the loop, or it will get reset every time through the loop.

Hint: The dictionary will be reset each time you run the program, so a sound that you enter during one run will not be there during the next run.

Hint: stop and new should not be in the dictionary. They should be the only things left in the if statement, and the sounds should happen in else

Hint: Use has_key on the animal name before you try to get it to make sure that you don't get a dictionary error.

Here is a new sample set of interactions. User text is in red

effect: cow
Moo!
effect: horse
Neigh!
effect: dog
Woof!
effect: cat
Meow!
effect: horse 5
Neigh! Neigh! Neigh! Neigh! Neigh!
effect: turtle
I don't know that effect!
effect: new turtle Crawl!
New effect turtle added
effect: turtle 3
Crawl! Crawl! Crawl!
effect: stop
Goodbye!

Problem 1: 50 points

Create a program called cards.py that deals hands of cards.

Hint: You can make an empty list like this: deck = []

Hint: You can use the append method of a list to add new items to the end

Hint: Try to get it to work without shuffling first. It will be easier to tell if you are missing cards.
