S4: RECAP UNTIL TESTING

What will be the output of the following code?

x = 10

if x > 5:

print("Greater")

else:

print("Smaller")

• Greater

• Smaller

• Error

• No Output

Answer explanation

The if statement checks if x is greater than 5. Since x is 10, the condition is True, and "Greater" is printed.

What will be the final value of sum after this code is executed?

num = 0

for i in range(5):

num = num + i

print(num)

• 5

• 10

• 15

• 20

Answer explanation

The loop iterates over a range of 5 numbers from 0 to 4. The sum of these numbers (0+1+2+3+4) is 10

Given the list my_list = ["apple", "banana", "cherry"]

What does print(len(my_list)) return?

• 3

• 6

• 15

• Error

Answer explanation

The len() function returns the number of items in an object. Since my_list contains three items, the result is 3.

What will be printed by the following code snippet?

fruits = ["apple", "banana", "cherry"]

print(fruits[1])

• apple

• banana

• cherry

• IndexError

Answer explanation

Arrays in Python are zero-indexed, so fruits[1] refers to the second element in the list, which is "banana".

What does the following code do?

user_input = 0

while user_input < 1 or user_input > 10:

user_input = int(input("Enter a number between 1 and 10: "))

• Repeats until a number less than 1 is entered.

• Repeats until a number greater than 10 is entered.

• Repeats until a number between 1 and 10 is entered.

• Causes an infinite loop.

Answer explanation

The code keeps asking for input until the user enters a number within the range 1-10 (inclusive).

How does the following code snippet calculate a running total?

numbers = [1, 2, 3, 4, 5]

total = 0

for index in numbers:

total = total + index

• Adds the index of each element to total.

• Adds the value of each element to total.

• Multiplies the value of each element with total.

• Subtracts the value of each element from total.

Answer explanation

The code iterates through the list numbers and adds each to the total variable, accumulating the sum of the list elements.

What kind of error will occur when the following code is executed?

for i in range(10)

print(i)

• Syntax

• Logic

• Execution

• Extreme

Answer explanation

The code is missing a colon : at the end of the for loop declaration, which is required in Python to indicate the start of the loop's body. This will result in a syntax error when the code is run.

Which module and function in Python can be used to generate a random integer between 1 and 10?

• import random; random.randint(1, 10)

• import math; math.random(1, 10)

• import random; random.range(1, 10)

• import math; math.randint(1, 10)

Answer explanation

The random module contains a function randint() which can generate a random integer between the two numbers inclusive.

What will be the content of my_list after executing the following code?

my_list = [1, 2, 3, 4, 5]

my_list[2] = 10

• [1, 2, 10, 4, 5]

• [1, 2, 3, 10, 5]

• [10, 2, 3, 4, 5]

• [1, 10, 3, 4, 5]

Answer explanation

The third element (index 2) of my_list is reassigned the value 10. Values start from 0.

Identify the line in the following code that checks for input validation:

user_input = int(input("Enter a number between 1 and 10: "))

if user_input < 1 or user_input > 10:

print("The number is out of range.")

else:

print("The number is within the range.")

• Line 1

• Line 2

• Line 3

• Line 4

Answer explanation

Line 2 contains an if statement that checks whether the user's input is less than 1 or greater than 10, which validates if the input is within the specified range. If the input is not within the range, it prints an error message.
