Output of Boolean expressions with logical operators

What is the output of this Python code snippet?

Python

a = True
b = False
print(a and not b)

A True

B SyntaxError

C None

D False

💡 Hint

Remember that 'not' reverses the Boolean value.

Variable 'a' is True, 'b' is False, so 'not b' is True. 'True and True' results in True.

Boolean conversion of different values

What will be the output of this code?

Python

print(bool(0), bool(1), bool([]), bool([0]))

A False False True True

B False True False True

C True False True False

D True True False False

💡 Hint

Zero and empty containers are False; non-empty containers and non-zero numbers are True.

0 and empty list [] are False; 1 and list with one element [0] are True.

Boolean evaluation in conditional expressions

What is the output of this code?

Python

x = 5
result = 'Yes' if x > 3 and x < 10 else 'No'
print(result)

A Yes

B No

C False

D True

💡 Hint

Check if x is between 3 and 10.

x is 5, which is greater than 3 and less than 10, so the condition is True and 'Yes' is printed.

Boolean logic with mixed operators

What will this code print?

Python

a = False
b = True
c = False
print(a or b and c)

A SyntaxError

B True

C None

D False

💡 Hint

Remember operator precedence: 'and' before 'or'.

'b and c' is 'True and False' which is False; then 'a or False' is 'False or False' which is False.

Understanding Boolean identity and equality

Which statement about Python Boolean values is correct?

A True equals 1 and is identical to 1

B True is 1 and False is 0

C True == 1 and False == 0 but True is not 1 and False is not 0

D False equals 0 but is identical to None

💡 Hint

Check the difference between '==' and 'is' in Python.

'==' checks value equality, so True == 1 is True; 'is' checks identity, so True is 1 is False because they are different objects.
