python: Execute a specific Python file.
$ python ${filename-py}
try on your machine
The command "python ${filename-py}" is not a valid command. It seems to be a template or placeholder command where ${filename-py} needs to be replaced with the actual name of a Python file (ending with .py extension).
To execute a Python script using the command line, you would use the command: "python filename.py". Here, "python" is the command to execute the Python interpreter, and "filename.py" is the name of the Python script file you want to run.
For example, if you have a Python script named "myscript.py", you would execute it using the command: "python myscript.py".

never run a command you are not sure if it is safe.
