Pythons is the most used programming language. It is used for different purposes like web development, data analysis, scientific computing, and automation tasks. Most of the developers think Python is fun as it’s very easy to understand like the English language. In this guide, we will provide step-by-step instructions on how to write and execute your first Python script. In this tutorial, you will learn how to write and execute your first Python script.
Step 1: Install Python
Before you can start writing Python scripts, you need to have Python installed on your system. Python is available for all major operating systems (Windows, macOS, and Linux) and can be downloaded from the official Python website . Choose the appropriate version for your operating system and follow the installation instructions provided.
Step 2: Choose a Text Editor or an Integrated Development Environment (IDE)
To write Python scripts, you need a text editor or an Integrated Development Environment (IDE). A text editor like Notepad or Sublime Text can be used, but using a Python-specific IDE provides additional features such as code completion, debugging, and project management.
Some popular Python IDEs include:
Choose the one that you like the most and install it on your system.
Step 3: Open the Text Editor or IDE
Launch your chosen text editor or IDE. If you are using a text editor, open a new file by selecting File > New or using the appropriate keyboard shortcut. If you are using an IDE, select File > New File or something similar.
Step 4: Write Your Python Code
Now it’s time to write your first Python script. In your text editor or IDE, type the following code:
This is the classic “Hello, World!” program, a simple script that prints the phrase “Hello, World!” to the console. It serves as a basic introduction to the syntax and structure of a Python script.
Step 5: Save the Python Script
Once you have written your code, save the file with a
.py extension. Choose a meaningful name for your script, such as
helloworld.py. Saving the file with a
.py extension is important because it indicates to the operating system that the file contains Python code.
Aftet that got to Select File > Save or use the corresponding keyboard shortcut to save your Python script.
Step 6: Execute the Python Script
To execute the Python script, you have a couple of options.
Option 1: Command Line Execution
Python scripts can be executed from the command line or terminal. Open the command line or terminal on your system and navigate to the directory where your Python script is saved.
Once you are in the correct directory, type the following command and press Enter:
helloworld.py with the name of your Python script if you chose a different name.
python instructs the system to run the Python interpreter and
helloworld.py is the name of the script to be executed. If all goes well, you should see the output
Hello, World! printed to the console.
Option 2: IDE Execution
If you are using a Python-specific IDE, you can execute the Python script directly from the IDE itself. Look for a “Run” or “Execute” button or a similar option, and click it. The IDE will internally invoke the Python interpreter and display the output in its console.
Congratulations! You have successfully written and executed your first Python script. Python is very easy to learn progaramming language. The above steps are very simple for implenting and run your first script.
