What is the output of the expression 7 // 2 in Python?

• A. 3
• B. 3.5
• C. 4
• D. 2

Answer: (A)

The expression 7 // 2 in Python uses the floor division operator, which is represented by the double forward slashes (//). This operator divides the left operand by the right operand and returns the largest integer less than or equal to the result of the division. In this case, dividing 7 by 2 results in 3.5, but because we are using floor division, we take the largest integer that is less than or equal to 3.5, which is 3. Therefore, the output of the expression 7 // 2 is indeed 3. This output clearly demonstrates how floor division truncates the decimal part of a number, only keeping the integer portion, which is a fundamental characteristic of this operator in Python.
