`if number/3==0:`

why do you use the division operator? To check if a number is divisible by 3 we need to use the modulo operator.

In Python we have two things that always confuses.

/ - This is division that gives you quotient

% - This is modulo operator that gives remainder after division.

To test if something is divided by some number ,It should leave remainder 0

so we need to find remainder?
