Can you explain what programming languages that run directly without prior compilation mean?

Programming languages that are executed directly without prior compilation are called interpreted. Unlike compiled languages, where the source code is first transformed into machine code (an executable file), interpreted languages are executed line by line using an interpreter.

For example, Python is an interpreted language. When you run a script, the interpreter reads and executes commands as they appear, without the need to create a separate executable file.

This is convenient for quick testing and development, but can be slower compared to compiled languages, as the interpreter performs additional work during program startup.
