Serhiy Storchaka <storchaka+cpyt...@gmail.com> added the comment: The from import already is much slower than simple import:
$ ./python -m timeit 'from encodings import aliases' 500000 loops, best of 5: 475 nsec per loop $ ./python -m timeit 'import encodings.aliases as aliases' 1000000 loops, best of 5: 289 nsec per loop The latter executes only C code if the module already is imported, but the former executes Python code. It may be worth to add the C acceleration for this case too. PR 4113 makes it yet slower: $ ./python -m timeit 'from encodings import aliases' 500000 loops, best of 5: 793 nsec per loop ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue21720> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
