The command is python3, not $python3.

I didn’t add the $, it is embedded in my terminal…

When I type python3 I get the expected message

But I cannot follow the lesson since I continue to get the error message posted above

I have no idea where all the other messages come from but here

you added a superfluous $ before python3 telling bash to expand an environment variable named python3 and since this does not exists the resulting command is “” which leads to the error message “bash: command not found”.

What do you get if you type “python3”?

I am not sure how to answer since I am unable to post a picture,

I have the expected >>> in Code

I know you think I added a superfluous $, I didn’t, it is already in my terminal

I do notice that my is all blue, not blue and yellow as the example

In the terminal? or, in Code?
