Once you open your python file in Emacs, you will need to start the python process with: M-x run-python or C-c C-p, which creates an inferior python shell buffer. This buffer will be created by a horizontal split, and the active buffer will be the one containing the python file.

Then you can do C-c C-c, which will send the current python buffer to the inferior python shell below. This is where you will see the output of your python file.

To switch to and from your python file buffer and the inferior python shell buffer, you can do C-x o.

If you accidentally close one of the buffers, you can switch between buffers with C-x C- and C-x C- and perform operations on the python buffer like the ones mentioned by Aaron Hall.

2. Did not define if (__name__ == '__main__'): block
