CSc 120 (Spring 25): Assignment 1

This assignment aims to review various Python concepts covered in CSc 110—specifically: reading from a file; lists; 2-D lists (lists of lists); simple conditionals and loops; and functions (including passing values into and out of functions).

General Requirements

1. You do not need to provide comments for the short problems.
2. For the long problems, your code should follow the style guidelines for the class. Your long programs must define a main() function. For reference, see the 01_Python_review lecture slides, from slide 110 to 114.
3. You may not use Python material not presented in class. Each long problem specification lists the language contructs that you are not allowed to use. If you don't know what any of those are, don't worry, because you cannot use them accidentally.

The process for turning in your solutions is as follows:

• Log in with your UA netid and password.
• Select Spring 25 on the pane on the left (click on the little triangle on the left).
• Select CSc 120 (click on the little triangle on the left).
• A blue bar with "Assg 01" should appear in the left pane under the name of the course. Click on this bar. This should cause seven problems to show up under the middle pane (Exercises): number2letter, concat_elements (two problems), column2list, grid_is_square, cv_match, and max_consec_sum.
• Select the problem you want to work on and click the button Load exercise (top right of the pane).
• Insert your code where it says "# your code here".
• Click the button Run it! (bottom right) to run your code on the test cases. The results will appear at the bottom of the screen.

The short problems for this assignment are the following:

1. Number to letter
