Saying "Hello, World!"
00:00 There’s a longstanding custom in computer programming that the first code written in a newly-installed language is a short program that displays the text, “Hello, World!”. In Python, running a “Hello, World!” program only takes a single line of code.
00:15
It’s a print() function call with the string, "Hello, World!", and to be more precise, it’s a capitalized Hello, followed by a comma, space, and then a capitalized World with an exclamation mark.

The string itself is not that important. The important part here is that the print() function will display a text to your screen when you run the Python program.
00:37 So in this course, you will use this line of code to explore similar ways of executing Python code. Let’s start with the first way of executing Python code, the REPL.
