Write a function named `evenOddString()` that takes a single string parameter.

If the length of the string parameter:

* is odd: `evenOddString()` should return the string parameter.
* is even, `evenOddString()` should return the string parameter concatenated with itself.

This is my code so far:

```
def evenOddString():
    len(var) % 2 != 0

```
