Python version 3 replaced the  reload(xxx) syntax with :
       import  imp

However, there are still lots of caveats, and reasons not to do it. 
This doesn't initialize the new module, it doesn't follow the imports
used there, it doesn't tell other modules of the code about this new
version of the module, ....  The feature is there for debugging, as far
as I know, and probably shouldn't be used in real code.

If your design is to have these variables' default values to come from
the file, then I'd suggest making it a data file, and not an import. 
Then you can literally save and restore those variables flexibly, and
without straining the language's limits.

Alternatively, just restart the process.
