Cheat.sh/python returns javascript result

```
lucy:~:% curl cht.sh/python/range
# JavaScript function similar to Python range()
#
# For a very simple range in ES6:

let range = n => Array.from(Array(n).keys())

# [user1969453] [so/q/8273047] [cc by-sa 3.0]
```

I would expect to get python result when I specified `python` in the query.

Start by reproducing the issue with `curl cht.sh/python/range`, then trace the request handling and language-selection entry point that serves this query. Done means the same request returns a Python `range` cheat sheet rather than the JavaScript result.
