Understanding Python Conditionals

What will be the output of the following code: if x > 10: print('Greater') elif x < 10: print('Lesser') else: print('Equal')?

• Greater

• Undefined

• Lesser

• Equal

Write a Python program using if-elif-else to check if a number is positive, negative, or zero.

• number = int(input('Enter a number: ')) if number < 0: print('Zero') elif number > 0: print('Negative') else: print('Positive')

• number = float(input('Enter a number: ')) if number >= 0: print('Zero') else: print('Positive')

• number = float(input('Enter a number: ')) if number > 0: print('Positive') elif number < 0: print('Negative') else: print('Zero')

• number = input('Enter a number: ') if number == 0: print('Positive') else: print('Negative')

How does the if statement differ from the if-elif-else statement in Python?

• The 'if' statement is used for defining functions.

• The 'if' statement checks one condition, while 'if-elif-else' checks multiple conditions in sequence.

• The 'if-elif-else' statement is used for loops only.

• The 'if' statement can check multiple conditions at once.

What will be printed if x = 5 in the following code: if x > 10: print('High') elif x == 5: print('Medium') else: print('Low')?

• Very High

• Low

• High

• Medium

Create a conditional statement that checks if a student has passed based on their marks (pass mark is 40).

• if (marks < 40) { return 'Passed'; } else { return 'Failed'; }

• if (marks == 40) { return 'Failed'; } else { return 'Passed'; }

• if (marks > 40) { return 'Failed'; } else { return 'Passed'; }

• if (marks >= 40) { return 'Passed'; } else { return 'Failed'; }

Explain the use of the else statement in an if-elif-else structure.

• The 'else' statement provides a default action when all other conditions fail.

• The 'else' statement can only be used with a single if condition.

• The 'else' statement is used to replace the if statement entirely.

• The 'else' statement is only executed if the first condition is true.

What will be the output of the following code: if a == b: print('Equal') elif a > b: print('A is greater') else: print('B is greater')?

• A is always greater

• B is always greater

• Equal regardless of values

• Depends on the values of a and b

Write a Python code snippet that uses nested if statements to determine if a number is even or odd and greater than 10.

• number = 5 if number < 10: print('Less than 10')

• number = 12 if number > 10: if number % 2 == 0: print('Even and greater than 10') else: print('Odd and greater than 10')

• number = 8 if number > 10: print('Even and greater than 10')

• number = 20 if number % 2 != 0: print('Odd and greater than 10')

How can you use logical operators in an if statement? Provide an example.

• if (num < 10 || num > 20) { console.log('Number is outside 10 and 20'); }

• if (num != 10) { console.log('Number is not 10'); }

• if (num == 15) { console.log('Number is exactly 15'); }

• if (num >= 10 && num <= 20) { console.log('Number is between 10 and 20'); }

What will happen if no conditions are met in an if-elif-else statement?

• The else block executes if present; otherwise, nothing happens.

• The elif block will execute by default.

• The program will crash if no conditions are met.

• The if block executes regardless of conditions.
