CLI not working

I was trying to make my CLI xCLI work in the console. Here is the terminal.
console>>>python3 _help

There’s no output (and im using an online ubuntu VM btw)
Also I was at the dir was at so i dont see any issues from
The project:!/mayank1234cmd?
Edit: python docs were recently changed so its ```
python -c ‘from foo import hello; print hello()’

I ran this on my own computer, you must have an error in your file because no output was returned for me.

@mayank1234cmd hello, when writing a CLI you should use the built-in argparse module
