Try Practice Questions

Which of these is NOT a valid variable name in Python?

total_marks

_score1

1student

name_2

Hurrah!

You’ve got this one right!

Incorrect answer

total_marks – Valid: starts with a letter; letters + underscore allowed.

_score1 – Valid: identifiers can start with _; digits allowed after.

name_2 – Valid: letter first, then letters, digit, underscore.

Next Question

What does the following code print?

total = 0
for i in range(1, 6):
    if i % 2 == 0:
        total = total + i
print(total)

Hurrah!

You’ve got this one right!

Incorrect answer

Only i = 4 counted; but loop also adds 2.

Would come from 2 + 3; code never adds odd 3.

Sum of all numbers 1 + 2 + 3 + 4 + 5; but code includes only even ones.

Next Question

What is the output of this code?

a = [1, 2, 3]
b = a
a = a + [4]
print(b)

[1, 2, 3]

[1, 2, 3, 4]

[4]

[1, 4]

Hurrah!

You’ve got this one right!

Incorrect answer

[1, 2, 3, 4] – Would be true if we had modified the list in-place (e.g. a.append(4)), which we didn’t.

[4] – No operation in the code creates a list with only 4.

[1, 4] – Mixing first and last elements; not the result of any list operation here.

People love using CodeBuddy

I started with the short Python videos on CodeBuddy and they’re so easy to follow. After that, the practice sets make sure I actually remember stuff, not just watch and forget.

Aarav

11th standard

With boards, I don’t have time for long courses. CodeBuddy’s small lectures are perfect. I finish one topic, solve a few sets and I’m done for the day.

Sanvi

12th standard

The weekly coding challenges are super fun. I try them every Sunday to check where I stand against other students. It actually pushes me to practice more.
