# Practice Creating and Using Functions in Python - task two

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

There is only one task. What is task two?

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!!

Thank you so much for taking the time to write that explanation out, it really helped me solidify my understanding!

whaoww...that helped thanks
