1. You want to automate renaming 300 files every month. Is Python a reasonable tool?
Yes. Repetitive work with clear rules is where a short script pays off quickly. No, Python is only for websites. Only if you are an expert programmer.
2. Which command checks the installed Python 3 version on macOS or Linux?
python3 --version python3 --install print(version)
3. What does type("42") return?
<class 'int'> <class 'str'> <class 'float'>
4. What is the difference between = and ==?
They are the same. = stores a value; == compares two values. == stores a value; = compares two values.
5. What does 7 / 2 return in Python 3?
3 3.5 1
6. You write print("Total: {total}") and the braces appear literally. What is missing?
The f before the quotes. A second print. A comma after total.
7. A user types " YES ". How do you compare it reliably to "yes"?
answer.strip().lower() == "yes" answer == "yes" int(answer) == "yes"
8. Which grade does score = 80 get with: if score >= 90 A, elif score >= 80 B, elif score >= 70 C?
A B C
9. What does break do inside a loop?
Skips to the next round of the loop. Exits the loop completely. Stops the whole program with an error.
10. Your while loop never ends. What is the first thing to look for?
The line inside the loop that should change the condition. A faster computer. A missing print statement.
11. Why should a function that calculates something use return instead of print?
So the caller can store and use the value. Because print does not work inside functions. Because return is faster.
12. You have orders where each order has a customer, total, and paid status. Which shape fits best?
A list of dictionaries One long string Three unrelated variables
13. int("abc") raises which error?
TypeError ValueError KeyError
14. When is try/except the right tool?
For errors you expect and know how to handle, like bad user input or a missing file. Around the whole program, so it never crashes. Instead of if statements for every rule.
15. Which habit will save you the most time as a beginner?
Reading the error message and fixing one thing at a time. Copying fixes from the internet until something works. Avoiding errors by writing very little code.
