How to Write Your First Python Script

Python is one of the most beginner-friendly programming languages, making it the perfect starting point for your coding journey. Writing your first Python script is an exciting step, and this guide will walk you through it step-by-step. Whether you’re completely new to programming or have dabbled in other languages, this tutorial will get you started.

Step 1: Set Up Your Environment

Before you write your first Python script, ensure you have Python installed on your computer.

1. Install Python
2. Download Python from the official website. Follow the installation instructions and ensure you check the box to add Python to your PATH during installation.
3. Choose a Text Editor or IDE
4. Use a text editor like Notepad++, or an IDE like PyCharm, VS Code, or IDLE (comes pre-installed with Python). IDEs are especially useful for beginners as they offer helpful features like syntax highlighting and debugging tools.

Step 2: Write Your First Python Code

Now that your setup is complete, let’s dive into writing your first script.

1. Open Your Text Editor
2. Open your preferred text editor or IDE and create a new file. Save the file with a .py extension (e.g., first_script.py).
3. Write a Simple Script
4. Start with the classic "Hello, World!" program. Type the following code into your file:

print("Hello, World!")

Step 3: Run Your Script

After writing your script, it’s time to execute it.

1. Using the Command Line or Terminal

• Open your command prompt (Windows) or terminal (Mac/Linux).
• Navigate to the directory where you saved your script using the cd command.
• Run the script by typing:

python first_script.py

1. Using an IDE

• If you’re using an IDE like PyCharm, simply click the "Run" button to execute your script.

You should see the output:

Hello, World!

Step 4: Experiment with Python Basics

Now that you’ve successfully written and run your first Python script, experiment with these beginner-friendly concepts:

1. Variables and Data Types

name = "Alice"
age = 25
print(f"My name is {name} and I am {age} years old.")

1. Basic Math Operations

a = 10
b = 20
print(a + b)
print(a * b)

1. Conditional Statements

number = 10
if number > 5:
    print("Number is greater than 5")
else:
    print("Number is 5 or less")

1. Loops

for i in range(5):
    print(i)
