1. Please write a Python 3 Program. Please show all of the outputs.

hint

to query the user for info at the command line, you use:

response = input("a prompt for the user > ") 

response will be a string of whatever the user types (until a ).

Procedure

In your student dir in the IntroPython2015 repo, create a session03 dir and put in a new list_lab.py file.

The file should be an executable python script. That is to say that one should be able to run the script directly like so:

$ ./list_lab.py 

(At least on OS-X and Linux)

you do that with this command:

$ chmod +x list_lab.py 

(The +x means make this executable)

The file will also need this on the first line:

#!/usr/bin/env python3 

This is known as the she-bang line it tells the shell how to execute that file in this case, with python3

NOTE: on Windows, there is a python launcher which, if everything is configured correctly look at that line to know you want python3 if there is more than one python on your system.

Add the file to your clone of the repository and commit changes frequently while working on the following tasks. When you are done, push your changes to GitHub and issue a pull request.

(if you are struggling with git just write the code for now)

When the script is run, it should accomplish the following four series of actions:

Create a list that contains Apples, Pears, Oranges and Peaches.

Display the list.

Ask the user for another fruit and add it to the end of the list.

Display the list.

Ask the user for a number and display the number back to the user and the fruit corresponding to that number (on a 1-is-first basis).

Add another fruit to the beginning of the list using + and display the list.

Add another fruit to the beginning of the list using insert() and display the list.

Display all the fruits that begin with P, using a for loop.

Using the list created in series 1 above:

Display the list.

Remove the last fruit from the list.

Display the list.

Ask the user for a fruit to delete and find it and delete it.

(Bonus: Multiply the list times two. Keep asking until a match is found. Once found, delete all occurrences.)

Again, using the list from series 1:

Ask the user for input displaying a line like Do you like apples?

for each fruit in the list (making the fruit all lowercase).

For each no, delete that fruit from the list.

For any answer that is not yes or no, prompt the user to answer with one of those two values (a while loop is good here):

Display the list.

Once more, using the list from series 1:

Make a copy of the list and reverse the letters in each fruit in the copy.

Delete the last item of the original list. Display the original list and the copy.
