Autovivification

Autovivification is like having a magic box. If you ask the magic box for something that doesn't exist yet, like a new toy or a new friend, the magic box will make it for you automatically. In computer programming, autovivification means that if you try to access something that doesn't exist yet in a programming language like Python or Perl, the language will make it for you automatically without you having to do anything else. This can be really helpful because it saves time and makes coding easier.
