Ruby differences between print formatting

I am starting to learn Ruby and I am using print and I saw that it can use two string formatting:

  1. print "#{var}"
  2. print "%r %d %r" % [var1,var2,var3]

Of course one difference is that in the first one you don't need to put the type of parameter you are passing, but what I really want to know is which one of this would work better for Ruby and some other tips that you could give me.

Thanks.

Most people use the former method as it automatically calls the .to_s method of the object to display the value. You can use this to your advantage by overriding the class's .to_s method to make it display whatever you wish.

Frankly I've never seen the second method used in any code I've looked at.
