How to run one line Python command in terminal?

Question

I want to get result of a Python function in terminal.

I tried to run the command:

$ python3 -m uuid uuid.uuid4().hex

And I expect to see the output be something like: '78cbf0fadaa34ff7ac3f7b965965e207'

Unfortunately I get error:

-bash: syntax error near unexpected token `('

You were close.

• The flag to run a single command is -c and not -m.
• You also need to import uuid so you can use it.
• You also need to use print() to actually see some output.
• Finally the whole passed command has to be in quotes.

$ python3 -c "import uuid; print(uuid.uuid4().hex)"
