Others have commented on stacktraces, so I wanted to mention that the debugging experience in VS Code (the replacement for Atom-based Juno) is much improved as of the past couple of months. Worth a revisit if you're using it already. Regarding stdlib support, I feel like it's a toss-up. For numeric and data processing code, Julia has a much richer stdlib whereas I need at least Numpy in Python (and even then, working with anything not array-shaped is a pain). For more systems-y stuff though, Python has a much fuller stdlib (e.g. reading/writing a bunch of archive formats). The end result for me is that scripting with Julia feels high friction, and doing anything which requires any kind of throughput with Python feels like pulling teeth.
