While on the subject you might also see something like

# 

Which can mean one of two things
1) It's a comment and you should not type it in
2) It's a root level command and you should su to root
   before running it. (# was the default Unix prompt
   for super users)

The latter usage is dying out and usually replaced with

$ sudo 

Which means that as an ordinary user ($) you type sudo
before the command. sudo should then prompt for your
user password before carrying out the command.

But the older # prompt style is still around in some
onlne tutorials.

You could also try

$ which python3

The $ is the OS prompt you are not supposed to type it in.

The error means that there a mistake in your input.
In this case you included the $ in your input.

Note that this is an OS error and nothing to do
with python itself.

Ah.  Do not include the leading "$" in the command that you're typing.
I'm assuming that you're reading some instruction that says something
like this:

---

Type the following into your command prompt:

$ type -a python3



If you are reading such an instruction, don't literally type the
dollar sign.  "$" is a convention that's used to indicate to you to
type the rest of the line into your command prompt.  It's because, by
default, the command shell will use "$" as its primary prompt to tell
the user that it is ready to accept a new command.
