hello
why does:
puts “Inspect:#{p(myDog)}”
give LESS verbose results than:
p(myDog)
?
is it that p returns an array, and puts only prints the first element of
arrays?
thanks

“p x” is a shorthand for “puts x.inspect”, i.e. it actually does the
printing. The “inspect” method is what actually returns a “verbose”
string. I suspect the intent of your first statement was:
puts “Inspect:#{myDog.inspect}”
If you call p during a string interpolation, you can expect the output
to appear before the whole strong you’ve asked it to print, which is
probably not what you wanted.

The method #p is meant to be used as a replacement for:
puts obj.inspect
It outputs itself, so you don’t want to interpolate its output like
you’re doing above. Try this:
print "Inspect: "
puts myDog.inspect
… vs …
print "p: "
p myDog
