Middle letter

This a problem set for you to work through

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

1. to build your skill applying computational thinking to a problem
2. 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 strings and basic math.

The Problem

You are going to be given a word. Your job is to return the middle character of the word. If the word's length is odd, return the middle character. If the word's length is even, return the middle 2 characters.

For example:

myString = "Torun"

...should return r, as 'r' is the middle character.

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?

# Thank you Merri! 

myString = "Toreun"

while myString:
    myString = myString[1:][:-1]
    if len(myString) == 2:
        print(myString)
    elif len (myString) == 1:
        print(myString)
