Smarkets is heavily invested in Python and this is why we've decided to be the Keystone sponsor of EuroPython 2018! In this talk, we'll tell you more about what we do at Smarkets, why we think we're a unique place to work, the interesting things we're doing at the Conference and of course how we use Python every day. We'll also tell you about some of our current challenges in upgrading from 3.6 to 3.7, evaluating asyncio in production and what we've learned from type hinting over the past two years.
