How to Run Python in Vim with the Current File?

To run Python code in Vim with the current file, you can use the built-in terminal emulator in Vim, also known as “vim-terminal” or “terminal-mode”. Here’s a step-by-step guide:

1. Open your Python file in Vim. For example, you can use the following command in your terminal:

vim myfile.py

2. Switch to terminal mode in Vim by pressing Ctrl + W, followed by :terminal, and press Enter. This will open a new terminal window within Vim.
3. In the terminal window, you can execute Python commands or run Python scripts just like you would in a regular terminal. For example, you can run a Python script by typing python myfile.py and pressing Enter, assuming that myfile.py is the name of the Python file you have opened in Vim.
4. After running the Python code, you will see the output or any errors in the terminal window within Vim.
5. To return to the normal Vim editing mode, press Ctrl + W, followed by :q to close the terminal window.

Note: If you want to run Python code with specific Python virtual environments or options, you can specify them in the command line. For example, you can use python3 instead of python if you have multiple Python versions installed, or you can use python -m venv to specify a virtual environment. You can also use Vim’s built-in mappings or plugins to customize the behavior of running Python code in Vim.
