What Is a Hello World in Python?

The hello world in Python is a simple script that outputs the phrase “Hello, World!” to the screen. It might seem trivial, but this program is the standard introduction to any programming language. By successfully running it, you confirm that your development environment is set up correctly and that you understand the very basics of writing and running a Python script.

Why Start with a Hello World Program in Python?

There are several reasons why every coding course and tutorial includes the hello world program in Python:

• Simplicity: It’s a small, easily achievable first goal.
• Immediate feedback: You instantly see the result of your work.
• Foundation: It introduces the structure and syntax of Python in the simplest way possible.

Starting with the hello world in Python program helps reduce anxiety about coding because you accomplish something in just a few minutes.

Step-by-Step Guide to Writing Your First Hello World in Python

Writing a hello world program in Python is extremely straightforward. Follow these simple steps:

1. Install Python

Download the latest version of Python from the official Python website.

2. Open an IDE or Text Editor

You can use tools like PyCharm, Visual Studio Code (VS Code), or even a simple text editor like Notepad.

3. Create a New File

Create a new file in your IDE or editor. After that, save the file with a .py extension, for example, hello.py.

4. Write the Code

Enter the following in the new file that you created in the previous step:

print("Hello, World!")

5. Run the Program

Open your terminal or command prompt, navigate to your file’s location, and type:

python hello.py

You should see the message:

Hello, World!

Alternately, use the run button in your IDE. This is shown in the following image circled in red in VS Code. As a result of clicking this button, the above output is shown in the terminal window that opens at the bottom of the VS Code IDE.

Congratulations! You have successfully written your first hello world in Python.

Key Concepts Behind the Hello World Program in Python

Even though the hello world program in Python is short, it introduces you to critical programming concepts:

• Syntax: Proper use of parentheses and quotation marks.
• Functions: Understanding that print() is a built-in Python function.
• Execution: How a Python interpreter reads and runs your code.

By grasping these concepts, you set the stage for more complex projects in the future.

Common Mistakes When Writing Hello World in Python

While the hello world in Python is simple, beginners often encounter a few common mistakes:

• Incorrect Syntax: Forgetting the parentheses (print "Hello, World!" instead of print("Hello, World!")) — in Python 3, parentheses are required.
• Spelling Errors: Small typos in print or inside the string can cause errors.
• File Extensions: Saving the file with the wrong extension (e.g., .txt instead of .py).

Carefully checking your code can help you avoid these issues and run your hello world program in Python successfully.

FAQ: Hello World in Python

What is the purpose of the hello world program in Python?
