Python IDLE Tutorial

Are you just starting your programming journey? Python is one of the most beginner-friendly programming languages to learn in 2025. In this guide, we’ll show you how to use Python IDLE and write your first few Python scripts. Let’s get started!

🔰 What is Python IDLE?

IDLE (Integrated Development and Learning Environment) is the built-in editor and debugger that comes with Python. It provides a simple and user-friendly interface for writing and running Python code, making it perfect for beginners.

Why Use Python IDLE?

• No extra setup required – comes with Python installation
• Lightweight and easy to use
• Perfect for writing small Python programs
• Provides both an interactive shell and a file editor

🛠️ How to Open Python IDLE

Step 1: First, install Python from the official website: https://www.python.org/downloads/

Step 2: After installation, locate IDLE:

• Windows: Search “IDLE” in the Start Menu
• macOS: Applications > Python > IDLE
• Linux: Run idle or idle3 In the terminal

✍️ Writing Your First Python Script

Step 1: Open the Python Shell

After launching IDLE, you’ll see the Python Shell (interactive mode).

>> print("Hello, World!")

Output: Hello, World!

Step 2: Create a New File

Click File > New File (or press Ctrl+N). This opens the script editor window.

Step 3: Write Your Code

# hello.py
print("Hello, World!")
name = input("What is your name? ")
print("Welcome to Python,", name)

Step 4: Save the Script

Click File > Save As and name it hello.py. Save it in a folder where you keep your projects.

Step 5: Run the Script

Press F5 or click Run > Run Module. The Python Shell will execute the code.

🧪 Learn Basic Python Concepts

1. Variables and Data Types

age = 25
height = 5.8
name = "Alice"
print(name, "is", age, "years old and", height, "feet tall.")

2. Conditional Statements

age = int(input("Enter your age: "))
if age >= 18:
    print("You're an adult!")
else:
    print("You're a minor.")

3. Loops

for i in range(5):
    print("This is line", i+1)

4. Functions

def greet(name):
    print("Hello,", name)

greet("John")

💡 Tips for Python Beginners

• Practice writing small scripts daily
• Use comments to explain your code
• Use the Python Shell to test small code snippets
• Refer to the official Python documentation
