The basic way to do output to screen is to use the print statement.
>>> print 'Hello, world' Hello, world
To print multiple things on the same line separated by spaces, use commas between them. For example:
>>> print 'Hello,', 'World' Hello, World
In Python 3, all print is a function and not a statement. Hence its arguments need to be surrounded by parenthesis. For example,
>>> print("Hello", "world")
Hello world
