Python is a widely used general purpose programming language whose design philosophy emphasizes code readability & constructs to enable clear programs on small & large scales.[1]

We recently presented at a meetup event and discussed how and why we started using Python at BlackRock. The speakers highlighted our experiences with the tools within Python as well as our plans to ensure optimal and efficient use of the technology at BlackRock going forward. The event also covered some key questions we had to answer along the way like how to ensure a consistent experience for all developers, how to manage different Python versions for different teams, how to upgrade external packages & not break everyone’s scripts, how to instill general good coding principles & more.
