Vim: Run selected code in a persistent REPL-environment

Question

R, Python, Scala etc. all come with REPL-environments, which I don\'t want to miss, however, most of the time editing text in them sucks, so I edit the code in vim, paste it

Answer 1

Try Conque:

""" Conque is a Vim plugin which allows you to run interactive programs, such as bash on linux or powershell.exe on Windows, inside a Vim buffer. """

It can easily be configured to open a Python interpreter, and a key mapping can be used to transfer the current line to it to be executed (F9 for the current line, F10 for the current file etc.).
