Could now we have all the above in a dictionary?  I'm not sure if the below is better... but I think it's easier to maintain.
```python
output = {'eve': 'eve', 'lyra': 'lyra', 'norh': 'norh', 'xrs': 'goes'}
for key, value in output.iteritems():
    if key in fname:
        return value
return None
```
