What is a high-level language?

  • A high-level language is a programming language that is designed to be easy to read and write.
  • High-level languages are closer to human language than machine language.
  • High-level languages are easier to learn and use than low-level languages.
  • High-level languages are portable, which means that they can run on multiple platforms.
  • High-level languages are more powerful than low-level languages.

What is Python used for?
