We can create long strings and maintain white space

long_string = "
I am a very very long
string that goes on for
ever"

puts long_string

I am a very very long
string that goes on for
ever

String formatting

puts "not true = #{not true}"

# Or

puts "not true = $s" % (not true)

not true = false
