Hello Foo - print
One way to improve the situation is to use the print function instead of the puts function to print to the screen.
That gave us a much nicer result as it did not print a newline after each item thereby moving the next one to the next line. However, it also did not print a newline at the end of the whole print operation, which would have been also less convenient. So in order to make it nicer we had to include \n at the end of our message to make it nicer. \n represent a newline so when we include \n in whatever we print the next thing will be printed on the following line.

person = 'Foo' print "Hello ", person, ", how are you?\n"
Hello Foo, how are you?
