by

Writing a Python file in Linux involves choosing between a text editor and an integrated development environment. If you are searching for how to create a python file in linux, you are likely a beginner or someone transitioning from another operating system. This guide will walk you through every method, from the simplest command-line approach to using full-featured IDEs.

Linux offers incredible flexibility for Python development. You can write code in a basic text editor like Nano or Vim, or use advanced tools like VS Code or PyCharm. Each method has its own advantages, and I will cover them all here.

By the end of this article, you will know multiple ways to create, edit, and run Python files on any Linux distribution. Let us start with the most fundamental method.

How To Create A Python File In Linux Using The Terminal

The terminal is the heart of Linux. Creating a Python file here is fast and requires no extra software. You only need a text editor and the Python interpreter.

Using The Nano Text Editor

Nano is a simple, user-friendly terminal editor. It is pre-installed on most Linux systems. To create a Python file with Nano, follow these steps:

  1. Open your terminal. You can usually do this with Ctrl+Alt+T.
  2. Type nano my_first_script.py and press Enter.
  3. Nano will open a blank file. Write your Python code here. For example: print("Hello, Linux!")
  4. Press Ctrl+O to save the file. Confirm the filename by pressing Enter.
  5. Press Ctrl+X to exit Nano.

You have now created a Python file. To run it, type python3 my_first_script.py in the terminal. The output will appear immediately.

Using The Vim Text Editor

Vim is more powerful but has a steeper learning curve. It is also pre-installed on many systems. Here is how to create a Python file with Vim:

  1. Open the terminal and type vim my_script.py.
  2. Press i to enter insert mode. You will see -- INSERT -- at the bottom.
  3. Type your Python code, such as print("Hello from Vim").
  4. Press Esc to exit insert mode.
  5. Type :wq and press Enter. This saves and quits.

Vim can be intimidating at first, but it is extremely efficient once you learn the basics. If you make a mistake, press Esc and type :q! to quit without saving.

Using The Gedit Or Mousepad Editors

If you prefer a graphical interface within the terminal, use Gedit (GNOME) or Mousepad (Xfce). These are simple GUI editors. To create a Python file:

  1. Open the terminal and type gedit my_script.py or mousepad my_script.py.
  2. A graphical window will open. Write your code.
  3. Save the file with Ctrl+S and close the window.

This method is great for beginners who are not comfortable with terminal-only editors. The file will be saved in your current working directory.

How To Create A Python File In Linux Using A File Manager

You can also create Python files using your file manager’s right-click menu. This is the most visual method. Here is how:

  1. Open your file manager (Nautilus, Thunar, Dolphin, etc.).
  2. Navigate to the folder where you want the file.
  3. Right-click on an empty space and select New Document or Create New File.
  4. Name the file with a .py extension, for example my_program.py.
  5. Double-click the file to open it in your default text editor.
  6. Write your Python code and save it.

This method works on all major Linux desktop environments. It is perfect when you want to organize files visually before coding.

How To Create A Python File In Linux Using An IDE

Integrated Development Environments (IDEs) offer syntax highlighting, debugging, and project management. They are ideal for larger projects. Here are the most popular options.

Using Visual Studio Code (VS Code)

VS Code is a free, cross-platform editor with excellent Python support. To create a Python file:

  1. Install VS Code from your package manager or the official website.
  2. Open VS Code and click File > New File.
  3. Write your Python code in the editor.
  4. Press Ctrl+S to save. Name the file with a .py extension.
  5. Install the Python extension from the marketplace for syntax highlighting and IntelliSense.

VS Code also has a built-in terminal. You can run your Python file directly from the editor by pressing Ctrl+Shift+` and typing python3 filename.py.

Using PyCharm

PyCharm is a dedicated Python IDE by JetBrains. It has a free Community edition. To create a file:

  1. Launch PyCharm and create a new project.
  2. Right-click on the project folder and select New > Python File.
  3. Enter a name for your file. PyCharm will automatically add the .py extension.
  4. Write your code and run it with the green play button.

PyCharm is feature-rich but can be heavy on system resources. It is best for professional development.

Using Thonny Or IDLE

Thonny and IDLE are lightweight Python IDEs. They come pre-installed with some Linux distributions. To create a file:

  1. Open Thonny or IDLE from your applications menu.
  2. Click File > New to create a new file.
  3. Write your code and save it with a .py extension.
  4. Run the file using the Run button or F5 key.

These tools are excellent for beginners because they include a built-in debugger and simple interface.

How To Create A Python File In Linux Using The Touch Command

The touch command creates an empty file instantly. This is useful when you want to set up multiple files quickly. Here is the syntax:

touch my_script.py

This creates a blank Python file in your current directory. You can then open it with any editor. To create multiple files at once:

touch script1.py script2.py script3.py

After creating the file, you need to add content. Use Nano, Vim, or any editor to write your code. The touch command is perfect for scaffolding projects.

How To Create A Python File In Linux With Proper Permissions

Sometimes you need to make a Python file executable. This allows you to run it like a command. Follow these steps:

  1. Create the file using any method above.
  2. Add a shebang line at the very top: #!/usr/bin/env python3
  3. Write your Python code below.
  4. Make the file executable with: chmod +x my_script.py
  5. Run it directly: ./my_script.py

This is common for scripts you use frequently. The shebang tells the system which interpreter to use. Without it, you must type python3 my_script.py every time.

Common Mistakes When Creating Python Files In Linux

Even experienced users make errors. Here are the most frequent ones and how to avoid them:

  • Forgetting the .py extension: Linux does not require file extensions, but Python does for proper recognition. Always add .py.
  • Using the wrong shebang: If you use #!/usr/bin/python instead of python3, it may point to Python 2 on some systems. Use #!/usr/bin/env python3 for portability.
  • Not saving the file: In editors like Nano, you must explicitly save. Check that your file exists with ls.
  • Running the wrong Python version: Some systems have both Python 2 and 3. Use python3 explicitly.
  • Permission denied: If you get a permission error when running, you forgot chmod +x or are not in the right directory.

How To Organize Python Files In Linux

Good organization saves time. Here are some best practices:

  • Create a dedicated folder for Python projects: mkdir ~/python_projects
  • Use descriptive filenames like data_analysis.py instead of test.py
  • Use virtual environments to manage dependencies. Create one with: python3 -m venv myenv
  • Keep your main script in the project root and modules in subfolders.

Virtual environments are especially important. They prevent conflicts between different projects. Activate one with source myenv/bin/activate before working.

How To Create A Python File In Linux For Web Development

Python is popular for web development with frameworks like Django and Flask. To create a web project:

  1. Create a project folder: mkdir my_web_app && cd my_web_app
  2. Create a virtual environment: python3 -m venv venv
  3. Activate it: source venv/bin/activate
  4. Install Flask: pip install flask
  5. Create your main file: touch app.py
  6. Write your Flask code and run it with python app.py

This workflow is standard for Python web development on Linux. The virtual environment keeps your project isolated.

How To Create A Python File In Linux Using Cron Jobs

Sometimes you need a Python script to run automatically. Cron jobs are perfect for this. First, create your Python file:

  1. Write a script that does a task, like backing up files.
  2. Make it executable with chmod +x backup.py
  3. Open your crontab: crontab -e
  4. Add a line like: 0 2 * * * /path/to/backup.py

This runs your script daily at 2 AM. Ensure the shebang line is correct and the file is executable. Test it manually first.
