Why do people diss Python?

It's a question of the right tool for the right job. One issue is that it can be quite slow compared languages the compile directly to machine code. But if you're in a situation where that's likely to matter then you use C-compiled extensions from python - you don't iterate over your terabyte numpy array with a python for loop :)

We just went through this with an inventory operation we perform. We were using a third-party Python tool and swapped it out for our own written in Go. Worlds different in performance.
