Re-loading updated modules

[Pierre Quentel]

Instead of exiting the interpreter, you can use reload() : see the
section "Built-in functions" in the library reference

"reload( module)
Reload a previously imported module. The argument must be a module
object, so it must have been successfully imported before. This is
useful if you have edited the module source file using an external
editor and want to try out the new version without leaving the Python
interpreter. The return value is the module object (the same as the
module argument). "
