e. 24
(Matching) Assume the following: val = 99 val += 1 Match the code with its output: print('The value is', 'val') print('The value is', val)' print("The value is:", 'val')
print('The value is', 'val') == The value is val print('The value is', val) == The value is 100 print("The value is:", 'val') == The value is: val
(Matching) After the execution of the following statements, the variable results will hold/ store what kind of data type? result = 123.456 result = int(123.456) result = "123.456" result = '123' result = 123 result = 123.0
result = 123.456 => float result = int(123.456)=> int result = "123.456" => string result = '123' => int result = 123 => result = 123.0 => float
(Matching) Match the expression to its result: 9//2 9/2 9%2 9**2
9//2 == 4 9/2 == 4.5 9%2 == 1 9**2 == 81
