Python 2 Conditionals Quiz

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

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

• print('Positive number')

• num = input('Enter a number: ')

• if num >= 0:

2. Write a Python program to find the largest of three numbers using if-else statement.

• if num1 >= num2 or num1 >= num3:

• if num2 <= num1 or num2 <= num3:

• if num1 <= num2 and num1 <= num3:

• if num1 >= num2 and num1 >= num3: largest = num1 elif num2 >= num1 and num2 >= num3: largest = num2 else: largest = num3

3. Write a Python program to check if a number is even or odd using if-else statement.

• if (num % 2 == 1): print('Even') else: print('Odd')

• if (num / 2 == 0): print('Even') else: print('Odd')

• if (num % 2 == 0): print('Even') else: print('Odd')

• if (num % 2 != 0): print('Even') else: print('Odd')

4. Write a Python program to find the largest number among three numbers using nested conditionals.

• if num2 > num3: largest = num2

• if num1 > num2: if num1 > num3: largest = num1 else: largest = num3 else: if num2 > num3: largest = num2 else: largest = num3

• if num1 > num2: largest = num1

• if num1 > num3: largest = num1

5. Write a Python program to check if a number is positive, negative or zero using nested conditionals.

• if num == 0: print('Positive') elif num < 0: print('Negative') else: print('Zero')

• if num > 0: print('Negative') elif num < 0: print('Positive') else: print('Zero')

• if num > 0: print('Positive') elif num < 0: print('Negative') else: print('Zero')

• if num < 0: print('Positive') elif num > 0: print('Negative') else: print('Zero')

6. Write a Python program to check if a year is a leap year using nested conditionals.

• if (year % 4 == 0): if (year % 100 == 0): if (year % 400 == 0): print(year, 'is a leap year') else: print(year, 'is not a leap year') else: print(year, 'is a leap year') else: print(year, 'is not a leap year')

• if (year % 400 != 0): print(year, 'is a leap year')

• if (year % 100 != 0): print(year, 'is not a leap year')

• if (year % 4 != 0): print(year, 'is a leap year')
