Chapter 3 :Programming for Everybody (Getting Started with Python) (Python for Everybody Specialization) Answers 2025

Question 1

What do we do to a Python statement immediately after an if statement to indicate that it should only execute when the condition is true?
✅ Indent the line below the if statement
❌ Start with #
❌ Underline it
❌ Begin with {

🧠 Explanation:
In Python, indentation defines code blocks. Code indented under an if statement executes only if the condition is true.

---

Question 2

Which of these operators is not a comparison/logical operator?
✅ =
❌ !=
❌ ==
❌ <=
❌ >=

🧠 Explanation:
= is the assignment operator, not a comparison operator.
Comparisons use ==, !=, <, >, <=, >=.

Question 3

What is true about the following code segment?

✅ Depending on the value of x, either all three of the print statements will execute or none will execute
❌ ‘Is 5’ will always print
❌ ‘Is 5’ will never print
❌ Only two will print

🧠 Explanation:
All three print statements are indented at the same level inside the if block, so they all run only if x == 5.

---

Question 4

When you have multiple lines in an if block, how do you indicate the end of the block?
✅ You de-indent the next line to the same level as the original if statement
❌ Use { }
❌ Use a colon on a separate line
❌ Omit a semicolon

🧠 Explanation:
Python uses indentation to determine block structure. The if block ends when the indentation returns to the previous level.

---

Question 5

Python gives an ‘Indentation Error’ on the second print statement. Why?
✅ You have mixed tabs and spaces in the file
❌ Python randomly emits errors 😄
❌ Python thinks “Still” is misspelled
❌ Program is too large

🧠 Explanation:
Indentation must be consistent (either all spaces or all tabs). Mixing them causes IndentationError.

---

Question 6

What Python reserved word indicates the false block in a two-way if test?
✅ else
❌ except
❌ iterate
❌ break

🧠 Explanation:
else: defines the block that runs when the if condition is false.

---

Question 7

What will this code print?

✅

🧠 Explanation:
x = 0 satisfies x < 2, so only the first condition is true.
Then it prints "All done" after the if block.

---

Question 8

For this code:

✅ This code will never print ‘Something else’ regardless of the value for x
❌ x = -22
❌ x = -2.0
❌ x = 2.0

🧠 Explanation:
Every number is either < 2 or >= 2.
The else block will never execute.

---

Question 9

Which will be the last line to execute successfully?

✅ 1
❌ 2
❌ 3
❌ 6

🧠 Explanation:
Line (2) will fail because 'Hello Bob' cannot be converted to int. So only line (1) executes successfully.

---

Question 10

What will the value of istr be after this code executes?

✅ -1
❌ NaN
❌ Random number
❌ false

🧠 Explanation:
The try block fails (int('Hello Bob') is invalid), so Python runs the except block, setting istr = -1.
