For example, if I want to do something like: $ env | grep "^XDG" In one python one liner like $ python -c 'import os;print("\n".join([f"{key}:{value}" for key, value in os.environ.items() if key.startswith("XDG ")]))' I can, but If I have things that require indentation I must change it to something like: $ python << EOF import os for key, value in os.environ.items(): if key.startswith("XDG"): print(f"{key}:{value}") EOF and although it can be embedded in a shell script or written in command line it has more than one line. Really is better add braces to python that write some docs explaining how to use it in command line? What are the issues with multi-line command line executions? Maybe I have missed some point. But this is the best reason I've read and I don't understand why is useful. regards, Javi PD: Python not only can be used in console, Python can be the console https://ipython.org/ipython-doc/stable/interactive/shell.html
