Hi
I typed 1 : 3 (typo)
which ended ruby with "expecting end of input"
What does this mean?
Thanks

If I had to guess of the top of my head it would mean ruby is expecting the
use of an "end" keyword somewhere in relation to some loop or construct
you've created.

You should start by providing exact data! The complete message is important:

$ ruby -ce '1 : 3'
-e:1: syntax error, unexpected ':', expecting end-of-input
1 : 3
   ^

So parsing breaks at the colon. There is no sequence beginning with a
colon that is legal in Ruby's syntax. You can find plenty of
information about context free languages and parser creation if you
want to understand more.

It means you didn’t read the output:

% ruby -e '1 : 3'
-e:1: syntax error, unexpected ':', expecting end-of-input
1 : 3
^

Please put more time and effort into your research before you spam a thousand people with your noise. You’ve been asked this multiple times by multiple people.

I'd advise you to simply google these questions/ Visit stackoverflow/ or
read ruby docs as the nature of questions are relatively easy to answer via
some searching online.

exactly.
I remember you can also use #method, but # is the comment-sign.
