I tried both:
(a) print "Please enter your name: "
and
(b) puts "Please enter your name: "
As I saw in my console and this first answer in this website , 'print' does not add a new line to the end of the output.
Are there any reasons to use 'print' instead of 'puts' beside the new-line reason?

47,314 PointsIs it an old post, so could be ruby has some changes since then? I just tried at my console the both examples and both works the same way. Results are as follows (all dots in both examples are printed with 2 seconds intervals:
2.1.0 :001 > 5.times do
2.1.0 :002 > puts "."
2.1.0 :003?> sleep 2
2.1.0 :004?> end
.
.
.
.
.
=> 5
2.1.0 :005 > 5.times do
2.1.0 :006 > print "."
2.1.0 :007?> sleep 2
2.1.0 :008?> end
..... => 5

If they now work the same, this is even better, because now you can do the 'waiting' dots with sleep properly :)
