I thought function calls was one of the decently optimized things in Python
Just code in C
- Just code in assembly
  
  Just punch the cards
  
  Just ritualistically wave a magnet near the computer
  
  Yes.
  
  Don’t write code, why do you need a computer to do your math? Just do it on paper ffs.
- The downvotes are hilarious. Being able to drop down to C is one of python's selling points, and the title of the post includes the name of the python ref implementation __C__Python.
  
  There is a difference being able to drop down in C and using exclusively C.
  
  One of the main advantage of python is being to quickly write code, and using C-based library / part of code written in C (or fortran, or rust for what it matters) when needed.
  
  "just write C" may lack a bit of nuance.
  
  Exactly.
  
  I don't really care, people will downvote for any number of reasons, and I know I was right, so it doesn't bug me
- How about no.
