 Hi again, for today's lesson we have a challenge. Write a function that checks if a number is odd or even. Okay, so we want to write a function that checks if a number is odd or even. Let's define our function, for example, let's call it even odd and that function will take one argument, one integer number, which will be either even or odd number. Okay, we know that number is even if it's perfectly divisible by number two. So, let us ask if the remainder of dividing of our number with two gives to us result zero and if it does, we will print to the screen that that number is even. So we will say number is even and if we have that remainder is one, then our number will be odd. So if our remainder of this dividing is equal to zero, then number is even and if our remainder is equal to one, our number is odd. Okay, I think that's it. Let's try to test our function. Let's use, for example, number five. Okay, number five is odd, even odd or, for example, number ten. Number ten is even. Okay, so we've successfully done the challenge. That's all in this lesson. Thanks for watching. Bye-bye.
