Welcome to the exciting journey of learning Python! As you embark on this adventure, the very first tradition in programming is to create a program that displays the simple yet iconic message: 'Hello, World!' This might seem basic, but it's a crucial step that confirms your development environment is set up correctly and introduces you to the fundamental concept of outputting information.
In Python, displaying text on your screen is achieved using the print() function. This function takes whatever you put inside the parentheses and shows it to you in the output. For our 'Hello, World!' program, we'll place the text we want to display, enclosed in quotation marks, inside these parentheses.
print("Hello, World!")Let's break down what's happening in that line of code:
print: This is the name of the function. It's like a command that tells Python to do something specific – in this case, to display output.(): These parentheses are essential for functions. They signal thatprintis a function and are used to pass information (called arguments) to it."Hello, World!": This is the argument we're passing to theprintfunction. The quotation marks tell Python that this is a string of text, not a command or a variable. Python will display this exact text.
When you run this simple program, you'll see the words 'Hello, World!' appear. This signifies that your Python interpreter is working, and you've successfully executed your first piece of Python code. Congratulations!
