View source for Reverse list of last names

[[File:square.png|right|frame|This a problem set for you to work through <ref>http://www.flaticon.com/</ref>]]

This is a problem set. Some of these are easy, others are far more difficult. The purpose of these problems sets are: 

# to build your skill applying computational thinking to a problem
# to assess your knowledge and skills of different programming practices


== What is this problem set trying to do ==

In this example we are learning about [[lists]], [[loops]], [[conditionals]],  and processing user input.

== The Problem ==

You are given a list of names in a list. The list will only have one first name and one last name. You must construct a program to process the names so they are in reverse order by last name. YOU WILL NOT BE GIVEN AN ALPHABETICAL LIST! 

for example: 

<syntaxhighlight lang="python">
names = ["Bill MacKenty", "Joe Shmoe", "Jan Kowalski", "Max Haltre"]

# the output should be: 

Joe Shmoe,  Bill MacKenty, Jan Kowalski, Max Haltre

</syntaxhighlight>

== How you will be assessed ==

Your solution will be graded using the following axis: 


'''Scope'''
* To what extent does your code implement the features required by our specification?
* To what extent is there evidence of effort?

'''Correctness'''
* To what extent did your code meet specifications?
* To what extent did your code meet unit tests?
* To what extent is your code free of bugs?

'''Design'''
* To what extent is your code written well (i.e. clearly, efficiently, elegantly, and/or logically)?
* To what extent is your code eliminating repetition?
* To what extent is your code using functions appropriately?

'''Style'''
* To what extent is your code readable?
* To what extent is your code commented?
* To what extent are your variables well named?
* To what extent do you adhere to style guide?

names = ["Bill MacKenty", "Joe Shmoe", "Jan Kowalski", "Max Zaltre"]

alphabet = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"

for name in names:
    first_letter_name = name.split(" ")[1][0]
    first_letter_names = names[0].split(" ")[1][0]
    if(alphabet.index(first_letter_name) > alphabet.index(first_letter_names)):
        current_name = name
        del names[names.index(name)]
        names.insert(0, current_name)
print(names)
