Python PCEM Exam: Conditional Statements (If, If-Else, If-Elif-Else)

Question 1: What will be the output of the following code?

x = 10
if x > 5:
    if x < 15:
        print("x is between 5 and 15")
    else:
        print("x is greater than or equal to 15")
else:
    print("x is less than or equal to 5")

1. x is between 5 and 15
2. x is greater than or equal to 15
3. x is less than or equal to 5
4. No output

Question 2: Given the following code, what will be printed?

a = 20
b = 30
if a > 10:
    if b > 25:
        print("Condition met")
    else:
        print("Condition not met")

1. Condition met
2. Condition not met
3. No output
4. Error

Question 3: What will be the output of this code snippet?

n = 5
if n == 5:
    print("n is 5")
elif n > 5:
    print("n is greater than 5")
else:
    print("n is less than 5")

1. n is 5
2. n is greater than 5
3. n is less than 5
4. No output

Question 4: What will be the result of the following code?

x = 7
if x > 10:
    print("Greater than 10")
elif x == 7:
    print("Equal to 7")
else:
    print("Less than 10")

1. Greater than 10
2. Equal to 7
3. Less than 10
4. Error

Question 5: Which of the following outputs can be generated by this code? (Select all that apply)

num = 15
if num < 10:
    print("Less than 10")
elif num < 20:
    print("Less than 20")
else:
    print("20 or more")

1. Less than 10
2. Less than 20
3. 20 or more

Question 6: Consider the following code. Which of the following outputs are possible? (Select all that apply)

x = 25
if x < 20:
    print("x is less than 20")
elif x > 20 and x < 30:
    print("x is between 20 and 30")
else:
    print("x is 30 or more")

1. x is less than 20
2. x is between 20 and 30
3. x is 30 or more

Question 7: Arrange the following steps in the correct order for evaluating multiple conditions in a nested if statement:

• If the first condition is true, evaluate the nested condition.
• Check if the first condition is true.
• If the nested condition is true, execute the corresponding code block.

Question 8: In a multiple if-elif-else conditional block, if the ______ condition is true, the corresponding code block is executed, and the subsequent conditions are ignored.

Question 9: The ______ statement is used to handle the case when none of the preceding if or elif conditions are met.

Question 10: Sort the following code snippets to correctly implement a decision structure that prints "Valid" if a number is between 1 and 10 (inclusive) and "Invalid" otherwise:

• if number >= 1:
• number = 5
• print("Valid")
• if number <= 10:
• else:
• print("Invalid")

Question 11: Fill in the missing code to check if a variable x is both greater than 10 and less than 20.

if x > 10 and ______:
    print("x is between 10 and 20")

Question 12: Fill in the missing code to print "Even" if the variable num is divisible by 2 and "Odd" otherwise.

if num % 2 == 0:
    print("Even")
else:
    print("______")

Question 13: Insert the correct condition to print "Equal" if a is equal to b.

if a ______ b:
    print("Equal")

Question 14: Insert the appropriate condition to print "Positive" if num is greater than 0, otherwise print "Negative".

if num > 0:
    print("Positive")
else:
    print("______")

Question 15: What will be the output of the following code?

x = 8
if x < 5:
    print("Less than 5")
elif x < 10:
    print("Less than 10")
else:
    print("10 or more")

1. Less than 5
2. Less than 10
3. 10 or more
4. No output

Question 16: What will be the output of this code snippet?

score = 85
if score >= 90:
    print("Grade A")
elif score >= 80:
    print("Grade B")
else:
    print("Grade C")

1. Grade A
2. Grade B
3. Grade C
4. No output
