Jody, This is one of the big differences between python and matlab: in matlab, if an m-file has changed within a session, the change is immediately effective. The python "import" statement is very different. If a module has been imported, then a subsequent "import" of it does not re-read the file, even if it has changed. There is a "reload" builtin function that will re-read a file, but it is rarely used. It reloads only the specified module, not modules that use it. Ipython has a recursive dreload (for deep reload) function, but I don't use that, either; I just do what you did, start a new instance of ipython. In ipython, the %run magic is useful for developing and modifying a single module or script at at time, making changes and testing without restarting ipython.
