How to add single quotes across a string in ruby?

I am iterating over a config.yml from from which parsing the values in a string form as follows:

machines:  
 A:
  ip: 10.11.12
  pass: vass
B:
  ip: 10.11.13
  pass: grass

The above config.yml is parsed as follows:

machines = YAML.load_file('machine.yml')
var=''
machines[A].each do |letters,hash|
   var += "[" + hash['ip'] + "]\n" + hash['pass'] + "\n"
end

The "var" value i am getting as : 

   "[10.11.12]\nvass\n[10.11.13]\ngrass\n"

but instead like above i dont want double quotes rather single quotes across complete atring as follows:

   '[10.11.12]\nvass\n[10.11.13]\ngrass\n'

So, please suggest how can have single quotes across the string.

Generally the puts will print the value of the string without double quotes in the console.

So may be you can use puts var so that double quotes are not getting printed. And now you can wrap your content with single quote using string interpolation.

var += "'#{actual_value}'"
