Which Python Operator Is Used to Find the Remainder (Modulo)?
Learn how to calculate the remainder of a division in Python using the modulo operator (%). Understand the difference between the remainder (%), true division (/), and floor division (//) operators for accurate calculations.
Question
Which expression yields the remainder of 29 divided by 6?
A. 29//6
B. 29%6
C. remainder(29, 6)
D. 29/6
Answer
B. 29%6
Explanation
% computes remainder → 5.
The expression 29%6 yields the remainder of the division.
In Python, the percent sign (%) is the modulo operator. It performs a division and returns the integer remainder. In the expression 29 % 6, the number 29 is divided by 6. The number 6 goes into 29 four full times (6 * 4 = 24), leaving a remainder of 5 (29 – 24 = 5). Therefore, 29 % 6 evaluates to 5.
The other options are incorrect for the following reasons:
A. 29//6 uses the floor division operator. It performs division and rounds the result down to the nearest whole number, returning the integer quotient 4.
C. remainder(29, 6) is not a standard built-in function in Python. Attempting to run this code would result in a NameError because the function remainder is not defined.
D. 29/6 uses the true division operator. It performs division and returns a floating-point number representing the exact result, which is 4.8333….
