Why code 1 or code 2 is not working i can't get the logic

Hi there,

You've correctly identified that using the mod operator % is the way forward here. You've also defined a method called even_odd, as required. This receives a number as a parameter.

What you want to do is to see if the number passed in is even. For that to be the case, using the mod operator and the number 2 will evaluate to zero if the parameter passed in is even, or not zero (it'll be 1, but hey) if the parameter is odd.

Let's make the method skeleton:

def even_odd(num):
  # return True if even

So, we want to use the mod operator on num. This would look like: num % 2. We want to know if that equals zero. We can compare this to zero using double-equals, ==. This gives us the ability to make the comparison with:

num % 2 == 0

You've thought about using an if statement to return the correct value. As it happens, you don't need to. The above expression will evaluate to either True or False. We don't need any more code. There no point in this:

var = True
if var == True:
  return True
else:
  return False

That's a lot of pointless code! So in our method, just return the result of the comparison:

def even_odd(num):
  return num % 2 == 0

i hope that makes sense.

Steve.

that totally made sense thnx...
