My Sublime Linter for `Python 2.7` reports that this line is not PEP8:

```
D = {k:get_distance(v) for k, v in D.items() if len(v) > 1}

```

in column `8` and `27`

but when I insert a space after colon (`:`), I get a red exclamation mark in Sublime.

How to make this line `PEP8` compliant?

**Update**

Sublime Text 2.0.2, build 2221 ;
Sublime Linter v1.8 ;
Python PEP8 Lint v2013.10.11.06

Code works and produces output without error
