Python:

  def f(x):  
    return x * x;  
  v=0.0  
  for i in range(100000000):  
    v = v + f(i)  

Execution time: 15 seconds

JavaScript:

  function f(x) { return x * x; } 
  var v = 0.0;  
  for(var i = 0; i < 100000000; i++) v += f(i);  

Execution time: 0.5 seconds

So calling a function in a for loop in Python is still 30x slower than in JavaScript which is an as-dynamic language. Good to see a 24% increase, but a 3000% increase should still be possible.

I did this test in python 3.10, not python 3.11, but I assume if they did have a 30x speedup from the inlined python to python function calls this would have been mentioned, but the fastest speedup listed is 1.96x faster.
