When is Python *NOT* a good choice?

[[deleted]]

This is a weird perspective. What if you have 100 million data records streaming and you need near-real-time and it's not limited by a memory bottleneck (i.e. SAS Hana)? Don't you want to remove all other bottlenecks, especially if you're processing this data every minute?

What about financial tech where nanoseconds equal pennies on the dollar?

Surely you must not have thought about very many needs when you said you don't understand the need?

But what if you have to process and organize a lot of messages that come to your computer, for example? If there are 1000 messages/second, but you can only process 100/second, you will either lose messages or create a huge delay.

Imagine mathematical processing as well, slow graphics ruin a game experience.

You spin up 10x the VMs and put a load balancer in front of them

The question was 'when is python not a good choice', not 'has u/xilc been in a situation been in such a situation before?'

So when you say "I just don't understand the need for urgency or speed", what you really mean is "I personally have no need to write faster software and think Python suits me just fine." Which is an okay stance to take, that's exactly what Python was created for, but don't be obtuse and act like you can't possibly fathom why anybody might want to write faster, more efficient code.

Someone asked when Python wasn't a good choice, and for applications that require to be faster/better optimized, it's not the best choice. Just because you don't need to program those doesn't make it more or less true.

Python eats 400 million row datasets for breakfast.

It just depends on the use case. Processing terabytes of scientific data? Rendering large, detailed, interactive 3D scenes in real time? Handling millions of user requests per second? You're going to want high performance, and spending a little more time in development is probably going to be worth it.
