To run a Python script on Linux, follow these steps:

  1. Open a terminal in Linux by pressing Ctrl+Alt+T or searching for "Terminal" in the applications menu.
  2. Navigate to the directory where your Python script is saved. Use the cd command followed by the path to your script's directory. For example, if your script is located in the "/home/user/scripts" directory, you would run: cd /home/user/scripts
  3. Check that you have Python installed. Type the following command to check the Python version: python --version If Python is not installed, you can install it by running the appropriate command for your Linux distribution, such as sudo apt install python3 for Ubuntu-based systems.
  4. Run the Python script using the python command followed by the name of your script file. For example, if your script file is named "my_script.py", you would run: python my_script.py If you have multiple versions of Python installed, you may need to use the specific version to run the script, such as python3 instead of python.


Make sure your script has executable permissions. You can set the executable permissions using the chmod command, like this:

1
chmod +x my_script.py


After setting executable permissions, you can run the script directly by typing ./my_script.py, assuming you are in the same directory as the script.


That's it! Your Python script should now execute and display any output or perform the intended tasks.

This covers the basic steps to run a Python script on Linux. Additionally, if the script requires any external libraries, you will need to ensure that those libraries are installed on your system. You can install Python libraries using pip, the Python package installer, like so:

1
pip install package_name


You can also create a virtual environment to isolate your Python project and its dependencies from the system Python installation. Here's a brief guide to setting up a virtual environment:

  1. Install virtualenv using pip:
1
pip install virtualenv


  1. Create a new virtual environment in your project directory:
1
virtualenv venv


  1. Activate the virtual environment:
1
source venv/bin/activate


  1. Install the required Python packages within the virtual environment:
1
pip install package_name


  1. Run your Python script within the activated virtual environment.


Remember to deactivate the virtual environment once you finish working on your project:

1
deactivate


Using a virtual environment is a good practice as it helps in maintaining project dependencies and prevents conflicts with system-wide packages.
