Executing current Python script in Emacs on Windows

Emacs is a powerful text editor that supports Python development through various plugins and modes. You can execute Python scripts directly within Emacs on Windows using the built-in Python mode and the python-shell-send-buffer command. In this tutorial, we'll walk through the steps to set up Emacs for Python development and execute a Python script.
Before you begin, ensure you have the following installed on your Windows system:
Emacs: You can download the latest version of Emacs for Windows from the official website (https://www.gnu.org/software/emacs/).
Python: Make sure Python is installed on your system. You can download the Python installer for Windows from the official Python website (https://www.python.org/downloads/windows/).
Install Emacs: Download and install Emacs on your Windows machine.
Launch Emacs: Start Emacs from the Start menu or the shortcut created during installation.
Install Python Mode (Elpy): You can use the "Elpy" package, which provides enhanced Python support for Emacs. To install it, add the following lines to your Emacs configuration file (~/.emacs or ~/_emacs, depending on your setup):
Configure Python Interpreter: Elpy should automatically detect your Python installation. You can verify this by opening a Python file (e.g., your_script.py) in Emacs and checking that the Python interpreter path is set correctly. If not, configure it using:
Now that you have Emacs and Elpy set up for Python development, you can execute a Python script directly from within Emacs.
Open Your Python Script: Open the Python script you want to execute in Emacs.
Edit and Save: Make any necessary changes to the script, and save it using C-x C-s or File - Save.
Execute the Script: To execute the entire script, press C-c C-c. This command sends the entire buffer to the Python shell.
Check the Python Shell: The Python shell should open in the Emacs buffer, displaying the output of your script.

Interact with the Shell: You can interact with the Python shell as you would in a regular Python interactive session. Type Python commands directly in the shell buffer and see the results.
View Output: To view the output of your script, scroll through the Python shell buffer.
You have now learned how to execute a Python script in Emacs on a Windows system using the Elpy package. Emacs provides a powerful development environment for Python, and you can customize it to suit your needs. Enjoy coding in Python with Emacs!
