I really don't get this one. Completely new to coding and struggling to remember it all, can anyone just walk me through MOD

The task asks `Create a function that determines if a specific value is odd`. Specifically:

• Create a function. This is done by include the keywork `def` in front of a variable and including a parameter list in parens, followed by a colon
```def function_name(parameters):
```
• Name the function `is_odd`
```def is_odd(parameters):
```
• have it declare a single parameter. This can be any variable name, let's use `value`
```def is_odd(value):
```
• return `True` if the value is not divisible by 2. The Python way to check if a value is even is to use the modulo operator % with 2. A zero result is even, a one result is odd
```is_odd_value = False
if value %2 == 1:
is_odd_value = True
```
• Return result
```    return is_odd_value
```

## Time to simplify the code

Instead of checking a Boolean (true/false) statement to set a Boolean value, just use the Boolean value directly

```    is_odd_value = value %2 == 1
return is_odd_value
```

But since `value % 2` returns either a 0 or a 1, and 0 is equivalent to `False` and 1 is equivalent to `True` you can use the results of the modulo directly to get an even result.

```    # adding not and changing 0 to 1
is_odd_value = not value %2 == 0
# or, simply
is_odd_value = not value %2
```

Returning the result:

```    # Return results
return is_odd_value
# or simply
return not value % 2
```

Post back if you need more help. Good luck!!

whaoww...that helped thanks
