ptpython vs Theremin

ptpython is an advanced Python REPL (read-evaluate-print loop). It offers features like syntax highlighting, autocompletion, multiline editing, and vim/emacs key bindings. It aims to provide a rich interactive environment for Python programmers.

The theremin is an electronic musical instrument that is controlled without physical contact by the performer. It detects the position of the performer's hands and varies pitch and volume accordingly, creating an eerie wavering sound.
