This. I rarely boot up Python for the tasks I need to do, and if they are, they are one of the following:

  • Assistant code for other coding language
  • Throwaway script
  • Prototype before using a faster language

Assuming an equivalent package is produced, what's the maintenance cost (factoring in coder availability) difference between the Python vs faster language implementations?

^^ therein lies the rub

Reminds of the expression, premature optimization is the root of all evil

if not swimming in funding, might be a darwinic move to choose the faster language and have to code everything yourself from scratch
