Languages have deep features. That's why people create new ones (except for PHP perhaps). You can write BASIC in any language you want, it's still BASIC. Languages systems or environments have still other deep features themselves. The library or module systems in Python or Perl or Raku do not work the same. Being able to write "a short, personally useful script.", is a great start. And does not count as "knowing Python" except for the purpose of inflated resumes. The clichés of complaining about "line noise" or WORN (write once read never) - since the fine article was about Perl - counts specifically as "not having learned Perl".
