What is the result of the expression 10 // 3 in Python?

• A. 3.33
• B. 3
• C. 4
• D. 30

Answer: (B)

The expression `10 // 3` in Python uses the floor division operator `//`, which divides the left operand by the right operand and then rounds down to the nearest whole number. In this case, when you divide 10 by 3, the result is approximately 3.3333. However, because of the floor division, Python truncates the decimal part and returns only the whole number portion of the result. Hence, the final output of `10 // 3` is 3. This behavior is distinct from regular division, which would give a floating-point result. Using floor division is particularly useful when you need an integer result without dealing with decimals.
