Figured it out by trial and error. I was trying to strip an object so I
datatyped it to a string and then used strip

username = cgi.params['username'].to_s.strip
profession = cgi.params['profession'].to_s.strip

This works unless there is something else I should use?
Coming from PHP so this is not easy.
