mixing strings and variables in ruby output

Question

I'm doing a codecademy tutorial to learn about Twitter's api. It requires us to print the response according to the following instructions

# ADD CODE TO PRINT THE TWEET IN "<screen name> - <text>" FORMAT

The following is saying that, although I'm parsing the response correctly, I'm not generating the correct output.

def print_tweet(tweet)
  user = tweet["user"]["name"]  
  text = tweet["text"]
  puts user + '-' + text

end

I'm so used to using instance variables in Rails that I'm not confident about simple Ruby like this. How should I write the function to generate output in this format?

"<screen name> - <text>"

Prefer string interpolation instead of string concatenation:

Replace: puts user + '-' + text

With:

puts "#{user} - #{text}"

You forget to add spaces around the - in your output. It should read

puts user + ' - ' + text
