Hey guys

am I doing this correctly? i get the correct answer on the console, however, dont get marks to carry on.

my_pets = {
“Jonny” => “dog”,
“Pete” => “cat”,
“James Bond” => “Lynx”
}

puts my_pets[“James Bond”]

3

not getting a syntax error neither

4

pets = Hash.new

pets[“Luna”] = “cat”

puts pets[“Luna”]

5

This example is a little bit broken. Tests won’t pass if the value is not a string. Keep an eye out for that!

After modifying the example code to change the values into numbers, it seems like the value prints to the console as expected.

pets = {
  "Stevie" => 1,
  "Bowser" => 2,
  "Kevin Sorbo" => 3
}
 
puts pets["Stevie"]
# 1 is printed to the console

Be sure to use the key in puts and not the value to get the expected result.
