Description: The platform module contains various version checks for systems such as cpython and ironpython. The file also contains a specfic case for ironpython which can be removed (see IronLanguages/ironpython3#1667) Removing the check improves the import speed as it avoids the compilation of a two regular expressions. %timeit _ironpython26_sys_version_parser = re.compile(r'([\d.]+)\s*' r'\(IronPython\s*' r'[\d.]+\s*' r'\(([\d.]+)\) on ([\w.]+ [\d.]+(?: \(\d+-bit\))?)\)' ) 383 ns ± 1.66 ns per loop (mean ± std. dev. of 7 runs, 1,000,000 loops each) Note: most of the compiled regular expressions in platform.py can be moved into the methods using them, as most results are cached. This would reduce the importtime for platform even further: Main: The speed of "import platform" is: 8.231517 +- 0.499458 [ms] Regular expressions adapted: The speed of "import platform" is: 7.182120 +- 0.726896 [ms] Issue: gh-102491
