I don't like the splitting of tuples across lines here, so just use the below, which is still perfectly in column limit:

```python
        data = [
            ('versions=1', {'version': '1'}),
            # default operator > and/or version 0.0.0 are not usable for default
            ('toolchains=%s' % self.tc_first, {}),
            # > not usable for default
            ('toolchains=%s > 1' % self.tc_first, {}),
            # == is usable
            ('toolchains=%s == 1' % self.tc_first, {'toolchain':{'name': self.tc_first, 'version': '1'}}),  
        ]
```
