Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✗

  3.5

  Why it's wrong here

  The single forward slash operator performs true division and would return 3.5, but the code uses the double forward slash operator, which is floor division. Floor division discards the fractional part and returns an integer when both operands are integers, so 3.5 is not the result displayed here.

• ✗

  1

  Why it's wrong here

  The value 1 is the remainder of the division 7 divided by 2, which is what the modulo operator percent would produce. The code uses the double forward slash operator instead, which returns the quotient rounded down. Therefore 1 is not the output of 7 // 2.

• ✓

  3

  Why this is correct

  The double forward slash operator performs floor division, dividing the left operand by the right operand and rounding the result down to the nearest whole number. Since both 7 and 2 are integers, Python returns an integer, and 7 divided by 2 is 3 with a remainder, so the floor is 3.

• ✗

  4

  Why it's wrong here

  Rounding 3.5 up to 4 would be the result of a ceiling operation, not floor division. Python's floor division always rounds toward negative infinity, so the fractional part is discarded rather than rounded to the nearest integer. The expression 7 // 2 yields 3, not 4.
