Because the 'help' function comes from site.py: def sethelper(): builtins.help = _sitebuiltins._Helper() If you're not importing site.py (eg "python3 -S"), you don't need the code for help(), but you'll always have type(). Basically it's a memory-saving thing. Critical vs optional. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
