I need to write a function that will print biggest odd number from three input arguments. 

Here is my code.

```
def oddn(x,y,z):
odd_number_keeper = []
for item in x,y,z:
    global odd_number_keeper
    if item % 2==1:
        odd_number_keeper = [item]
        return max(odd_number_keeper)
    else:
        print 'No odd number is found'

```

My codes seem is not working. Any ideas how i can modify this code?
