Consider the following code. x = oat ('23 42') Which of the following expressions will evaluate to 2?

Question

Options

• Aint(x) + False
• Bbool(x) + True
• Cstr(x)
• Dbool(x)

• A
  16% (6)
• B
  71% (27)
• C
  8% (3)
• D
  5% (2)

Explanation

x = float('23.42') (the fl is cut off by the question's formatting), so x holds the float value 23.42.

Option B is correct because bool(x) evaluates to True (any non-zero number is truthy), and in Python, True has an integer value of 1. So bool(x) + True becomes 1 + 1 = 2.

Why the distractors fail:

• A - int(x) + False truncates 23.42 to 23, then adds 0 (False = 0), giving 23, not 2.
• C - str(x) returns the string '23.42', which is text, not an integer.
• D - bool(x) alone returns True, which equals 1, not 2.

Memory tip: Remember that in Python, True == 1 and False == 0, so booleans participate in arithmetic. When you see bool + bool or bool + int, mentally substitute 1 or 0 and do the math - True + True is always 2.
