In this tutorial, we'll guide you through the process of running Python scripts on the Ubuntu command line. Whether you're a beginner or an experienced developer, understanding how to execute Python scripts in a terminal environment is a fundamental skill.
First, open a terminal on your Ubuntu system. You can do this by searching for "Terminal" in the application launcher or by using the keyboard shortcut Ctrl + Alt + T.
Navigate to the directory where your Python script is located. You can use the cd command to change directories. For example, if your script is in the "Documents" directory, you can use:
If your Python script is not yet marked as executable, you'll need to do so using the chmod command. Replace your_script.py with the actual name of your Python script:
This command grants execution permission to the script.
Now, you can run your Python script using the python3 command followed by the script's name. For example:
If your script is compatible with Python 2, you can use python instead of python3. However, it's recommended to use Python 3, as Python 2 is no longer supported.
You can simplify the process by adding a shebang line at the beginning of your script. This line specifies the interpreter to be used. Open your script in a text editor, such as nano or vim, and add the following line at the top:
Save the file, and make it executable if you haven't already (Step 3). Now, you can run the script directly without specifying the Python interpreter:
Virtual Environments: Consider using virtual environments to manage dependencies for your Python scripts. This helps to isolate project-specific dependencies.
Python Versions: If you have multiple Python versions installed, be explicit about the version you want to use (e.g., python3).
Troubleshooting: If you encounter issues, check for error messages in the terminal. They often provide valuable information about what went wrong.
Congratulations! You've successfully learned how to run Python scripts on the Ubuntu command line. This fundamental skill is essential for any Python developer, allowing you to execute and test your scripts in a terminal environment.
