Interactive programming in Python is a pain for all but the simplest statements; I much prefer to useemacs (even on windows) and use Ctrl-C, Ctrl-C to execute the buffer. I'm sure there are other similartools to do the same thing.Adam DePrince wrote:> Chris Richard Adams wrote:> >> > How can I create a loop - interactively.
