I suspect that site is some kind of in-joke. E.g. read the regex-redux example in say c#, now look at the go version, now the python version… It’s not really what you’d expect for a site called computer language benchmarks game. Each example just calls out to a very fast c library (pcre2) to perform the heavy lifting regardless of which language is being “benchmarked”. Seems a pretty pointless site. The other examples have similar nonsense.

        And? CPython is implemented in C. Here's some of a comment from _operator.c "This module exports a set of functions implemented in C corresponding\n\ to the intrinsic operators of Python. For example, operator.add(x, y)\n\ is equivalent to the expression x+y." Why wouldn't you expect that CPython regex would "ultimately" be written in C?

    That's correct, the Python program that uses pcre2 is faster. The slower program is an example from that website of a regex program which does not " just calls out to a very fast c library (pcre2)…".

  Do you mean Python program[mer]s are less bored ?
  - Zababa 5y ago
    Oh no, the programs aren't bored at all, they are very busy, which is the problem. Edit to answer yours: There may be less Python programmers that are bored, or less performance-oriented Python programmers.
