Those ten lines of code may require ten thousand lines ...

I understand and appreciate all that. It's true of any modern programming language nowadays, not just python.

Python is interpreted at run-time, line by line, like other script languages (e.g, basic, perl, php, ruby).

An interpreted language is a programming language in which programs are 'indirectly' executed ("interpreted") by a interpreter program running in the background. This interpreter program eats up hardware resources a single running "compiled program" wouldn't in most cases.

A compiler is a computer program (or set of programs) that transforms source code, written in a programming language (the source language), into another computer language (the target language, often having a binary form known as object code).

A compiled language (e.g. C/C++, Pascal, even VB, etc.) is converted into minimal machine code and then 'directly' executed by the host CPU/MPU. It's faster and requires fewer hardware resources.

I realize you probably already know most of this - I'm just not sure why you seem to be stumbling over it. Anyway, I just wanted to spelled it out for those who may read the thread and do not know the difference.

Python 3 code that generates a window and exit button. Not sure how the formating will turn out. :-)
