The result of the following addition: 123 + 0.0

Question

Options

• Acannot be evaluated
• Bis equal to 123
• Cis equal to 123.0

• A
  14% (3)
• B
  5% (1)
• C
  81% (17)

Explanation

When an integer and a float are added together, Python (and most languages) perform type promotion: the integer is automatically converted to a float before the operation, so the result is 123.0 - a float, not an integer. This makes C correct.

A is wrong because the expression is perfectly valid - Python handles mixed int/float arithmetic without error. B is wrong because even though the numeric value is equivalent to 123, the type has changed: 123 is an int, while 123.0 is a float, and the question asks about the result of the addition (which is a float).

Memory tip: Think of it as the float "infecting" the result - any arithmetic involving a float always produces a float, no matter how small or trivial the float operand is. x + 0.0 is a common Python pattern used intentionally to force a value into float type.
