Title: Running Python Scripts from the Windows Command Line - A Step-by-Step Tutorial
Introduction:
Python is a versatile programming language used for various purposes, and running Python scripts from the Windows command line is a fundamental skill for any Python developer. This tutorial will guide you through the process of executing Python scripts using the Windows Command Prompt, providing step-by-step instructions and code examples.
Step 1: Install Python
Before you can run Python scripts, ensure that Python is installed on your system. You can download the latest version from the official Python website (https://www.python.org/downloads/) and follow the installation instructions.
Step 2: Set Up Environment Variables
During the installation process, you may have the option to add Python to the system PATH. If not, you can manually add it to the PATH by following these steps:
Step 3: Create a Python Script
Now, let's create a simple Python script. Open your preferred text editor (e.g., Notepad, VSCode) and create a file named hello.py with the following content:
Save the file in a location of your choice.
Step 4: Open the Command Prompt
To open the Windows Command Prompt, press Win + R to open the Run dialog, type cmd, and press Enter.
Step 5: Navigate to the Script Directory
Use the cd command to navigate to the directory where your Python script is located. For example, if your script is on the desktop, you can use:
Step 6: Run the Python Script
Once you're in the correct directory, use the python command followed by the script's filename to run the script. For our example:
If you're using Python 3, you might need to use python3 instead:
After executing the command, you should see the output:
Congratulations! You have successfully run a Python script from the Windows Command Line.
Conclusion:
In this tutorial, we covered the essential steps to run Python scripts from the Windows Command Line. Remember to have Python installed, set up environment variables, create a Python script, open the Command Prompt, navigate to the script directory, and execute the script using the python command. This foundational knowledge will empower you to work with Python seamlessly on a Windows system.
