Execute python commands passed as strings in command line using python -c

You can use -c to get Python to execute a string. For example:

python3 -c "print(5)"

However, there doesn’t seem to be a way to use escape characters (e.g. \n). So, if you need them, use a pipe from echo -e or printf instead. For example:

$ printf "import sys\nprint(sys.path)" | python3
