What symbol is used for the modulo operation in Python?

• A. +
• B. %
• C. #
• D. *

Answer: (B)

The symbol used for the modulo operation in Python is the percent sign (%). The modulo operation calculates the remainder of a division between two numbers. For example, if you have the expression 10 % 3, it evaluates to 1 because when 10 is divided by 3, the quotient is 3 with a remainder of 1. This operation is particularly useful in various programming scenarios, such as determining if a number is even or odd (using number % 2) or cycling through values in a range.

In Python, the percent sign is dedicated specifically to this operation, distinguishing it from addition, subtraction, or multiplication, which use the symbols +, -, and *, respectively. This clear differentiation helps in writing and understanding code clearly, as each operator has a specific purpose.
