Module 31 Knowledge Check

There are 10 questions in this knowledge check.

You need to answer at least 6 questions correctly to pass.

You can attempt this check as many times as you need.

According to Computational Thinking principles, what is typically the FIRST step when tackling a large, complex programming project?

Immediately start writing code. Decompose the problem into smaller, manageable parts. Choose the most advanced algorithm possible. Optimize the code for speed before it's written.

How does the CT concept of 'Abstraction' primarily help during project preparation?

By making the code run faster. By hiding complex details and focusing on essential features. By ensuring every possible error is caught initially. By writing all the code in a single large file.

Which of these activities is most associated with the 'Algorithm Design' part of project preparation?

Choosing variable names. Deciding the exact colors for the user interface. Planning the step-by-step logic the program will follow. Writing comments in the code.

You need to create a simple program that reads a list of names from a file, greets each person, and saves the greetings to another file. Which concepts learned earlier are MOST LIKELY to be combined?

Dictionaries, Recursion, and Math module. File Reading, File Writing, Loops (for), and String manipulation. Exception handling, Tuples, and `while` loops only. Object-Oriented Programming and Importing `random`.

Why is the 'Evaluation' step crucial after developing a part of your project?

To make the code look prettier. To immediately start the next feature. To test if it works correctly, find bugs, and see if it meets requirements. To add more comments.

If your project involves storing player names and their corresponding high scores, which data structure is generally most suitable for easy lookup of a score given a name?

A List A Tuple A Dictionary A simple String variable

During project preparation, what is the primary benefit of using functions?

To make the program always run faster. To break down the code into reusable, logical blocks, improving organization and readability. To eliminate the need for variables. To automatically handle all errors.

When debugging a part of your project that isn't working, what is a common and effective first step?

Rewrite the entire section from scratch immediately. Add `print()` statements to check variable values at different points. Assume the computer made a mistake. Remove all comments to simplify the code.

Integrating different parts of your code (like functions, loops, file handling) requires careful planning primarily related to:

How data flows between the different parts. Using the shortest possible variable names. Ensuring every line has a comment. Making the code as complex as possible.

What is the main purpose of using `import` (e.g., `import math`) when preparing a larger project?

To make your script file smaller in size. To access pre-written code (functions, variables) from modules, promoting reusability. To automatically document your code. To change the version of Python being used.
