How do I execute this code using gVim?
If I use either
:! python pi.py or
:w !python - then I get the following:
You don't need to save the file, you can run the current buffer as stdin to a command such as
python by typing:
:w !python -
(The hyphen at the end probably isn't necessary, python will generally use stdin by default)
edit: seeing as you are new to vim, note that this will not save the file, it will just run it. You will probably want to learn how to save your file.
