i = true and false in Ruby is true?

Question

Am I fundamentally misunderstanding Ruby here? I\'ve been writing Ruby code for about 2 years now and just today stumbled on this...

ruby-1.8.7-p249 > i =         


        

Answer 1

As others have elucidated above, the keyword and is used when you want to put two different statements on one line. It is just a nicer way of making your code readable.

Thus,

 i = true and false 

implies

i = true; false #(a less widely used code layout in ruby)

or which is the most straightforward way:

  
 i = true
 false 

So, the output is correct. Otherwise, if you were expecting false, then use the boolean and &&.
