401000 Authentication Error in Microsoft Translator API

Entering the following code at the MAC terminal results in an error.

Microsoft Azure only configures the Translator in Marketplace and enters the key and the key in the Endpoint column into the Ocp-Apim-Subscription-Key.

Is there anything else to set up?

Will I be able to use it after a while after setting it up?

Once this problem has been cleared, I would like to use it in Python's program.

Thank you for your cooperation.
