This isn't a PEP-8 requirement, but I'd <3 it if you kept your parentheses balanced.

```
parser = OptionParser(
    usage="usage: %prog [options] filename",
    version="%prog 1.0"
)
```

This *is* a PEP-8 requirement, but absolutely no tabs please -- each indentation should be four spaces.  I used to like tabs too (and I still kind of do), but the PEP is quite clear, and it's important that we all follow the same guidelines.
