Quiz: Chapter 6 :Python Data Structures (Python for Everybody Specialization) Answers 2025

Question 1

What does this Python program print out?

✅ Hellothere
❌ Hello
❌ Hello there
❌ 0

🧠 Explanation:
The + operator concatenates strings directly, without adding a space unless you include one manually.

Question 2

What does this program print out?

✅ 42
❌ x2
❌ 402
❌ int402

🧠 Explanation:
x is converted from a string '40' to an integer 40, then 40 + 2 = 42.

Question 3

How to print the letter q from the string:

✅ print(x[9])
❌ print(x[8])
❌ print(x[7])
❌ print(x[q])
❌ print(x[-1])

🧠 Explanation:
Indexing starts at 0.
x[9] → 'q'
F(0) r(1) o(2) m(3) (4) m(5) a(6) r(7) q(8) u(9) ... ← careful! actually index 8 gives 'q'
✅ Correction: correct index is 8 (so right answer is print(x[8])).

✅ Final Answer: print(x[8])

Question 4

How to slice 'uct' from the string:

✅ print(x[14:17])
❌ print(x[15:18])
❌ print(x[14:3])
❌ print(x[14+17])
❌ print(x[14/17])

🧠 Explanation:
String slicing uses x[start:end], taking characters from index 14 up to (but not including) 17.

Question 5

What is the iteration variable?

✅ letter
❌ in
❌ ‘banana’
❌ for
❌ print

🧠 Explanation:
letter takes on each character from 'banana' in each loop iteration.

Question 6

What does this print out?

✅ 42
❌ bananabanana…
❌ banana7
❌ 0

🧠 Explanation:
len('banana') = 6 → 6 * 7 = 42

Question 7

How to print all uppercase:

✅ print(greet.upper())
❌ console.log(greet.toUpperCase()); (JavaScript)
❌ print(uc($greet)); (PHP)

Which of the following is not a valid Python string method?
✅ boldface()
❌ upper()

Question 9

What will this code print out?

✅ .ma
❌ mar
❌ uct
❌ 09:14

🧠 Explanation:
data.find('.') gives index of first ., which occurs before "mar..."
