Re-programming Arduino Via Python?

[eduardo3rd]

I'm working on a project to create a device that a few (less than 20) users will connect to their home wi-fi networks. The wi-fi module that I am using requires that the wi-fi network name, encryption type, and password be hardcoded into the sketch before it can connect to a netwok. Since I would prefer to allow users to modify this information on their own I plan to write a simple GUI in Python that will hopefully take the info from the user and upload it to the arduino via the serial port. However, I can't seem to find a way to force the arduino to save these values after it is reset. Is there a way to permanently modify an arduino sketch without running the IDE, or is that the only option?

Might try the Arduino EEPROM library.
