Quiz – Module 3 – Introduction to Python

Question 1

What is the output of print("a", "b", "c", sep="-")?

a b c
abc
a-b-c
a - b - c

Correct: c) The sep parameter replaces the default space separator with "-".

Question 2

What data type does input() always return?

int
str
The type of whatever the user enters
float

Correct: b) input() always returns a string, even if the user types a number. You must convert it with int() or float() if you need a number.

Question 3

Which code correctly gets an integer from the user?

age = input("Age: ")
age = int("Age: ")
age = input(int("Age: "))
age = int(input("Age: "))

Correct: d) input() gets the string from the user, then int() wrapping it converts that string to an integer.

Question 4

What does the end parameter in print() control?

What character is printed at the end (default is newline)
What character separates the values
How many times to print
The last value to print

Correct: a) By default, print() adds \n (newline) at the end. The end parameter lets you change this to a space, empty string, or anything else.

Question 5

What does f"{3.14159:.2f}" produce?

3.1
3.141
3.14
3.14159

Correct: c) The :.2f format specifier rounds to 2 decimal places, producing 3.14.

Question 6

What is the output of this code?

name = "Alice"
print(f"Hello, {name}!")

Hello, {name}!
Hello, Alice!
Hello, "Alice"!
Error

Correct: b) The f prefix makes it an f-string, so {name} is replaced with the value of the variable name.

Question 7

What does f"{0.75:.1%}" produce?

0.75%
75%
0.8%
75.0%

Correct: d) The % format specifier multiplies by 100 and adds a percent sign. .1 gives 1 decimal place, producing 75.0%.

Question 8

What is the output of print("Hi", end="") ; print("there")?

Hithere
Hi there
Hi and there on separate lines
Error

Correct: a) end="" removes the newline after "Hi", so the next print continues on the same line with no space, producing Hithere.

Question 9

What does f"{1000000:,}" produce?

1000000
1.000.000
1,000,000
,1000000

Correct: c) The :, format specifier adds comma separators for thousands.

Question 10

What happens when you run: num = input("Number: ") and the user types 42?

num is the integer 42
num is the string "42"
num is the float 42.0
Python auto-detects it as an integer

Correct: b) input() always returns a string, regardless of what the user types. The value is "42" (a string), not the number 42.

Question 11

What is the difference between "Hello, " + name and print("Hello,", name)?

There is no difference
Concatenation adds a space; commas do not
Commas can only be used with strings
Concatenation does not add a space; commas do

Correct: d) Concatenation with + joins strings exactly as-is (no automatic space). print() with commas automatically adds a space between values.

Question 12

Which approach is generally recommended for formatting strings in modern Python?

String concatenation with +
The .format() method
f-strings (f"...")
The % operator

Correct: c) f-strings (introduced in Python 3.6) are the modern, preferred approach. They are more readable and more concise than other methods.
