In ​Writing and Running a Program​, built-in function print was used to print values to the screen. We will use print to print messages to the users of our program. Those messages may include the values that expressions produce and the values that the variables refer to. Here are two examples of printing:

Function print doesn’t allow any styling of the output: no colors, no italics, no boldface. All output is plain text.

The first function call does what you would expect from the numeric examples we have seen previously, but the second does something slightly different from previous string examples: it strips off the quotes around the string and shows us the string in a human-readable form, rather than its character representation. This example makes the difference between the two even clearer:

And the following example shows that when Python prints a string, any escape sequences are converted to a form that humans expect:

The previous example shows how the tab character \t can be used to lay values out in columns.

In ​Creating a Multiline String​, we saw that \n indicates a new line in multiline strings. When a multiline string is printed, those \n sequences are displayed as new lines:

Function print takes a comma-separated list of values and prints the values with a single space between them…
