Need Help to interface 100 Proximity Sensors with Arduino/other to Python Application

We have a hardware device that has 100 ports. We have an issue where if we plug in a device into the port, and if the device is bad it may not communicate to our software, so we do not know the port is occupied or not... We were thinking about adding a proximity sensor to each port/bay that can let us know if there is a device added to the slot, and if the software doesn't recognize the device, we will send a command to an LED to indicate it is failed.

what do you think would be the best way to control 100 sensors and feed the occupied status back to our python application? We were thinking arduino with Proximity sensors, but it seems that it is limited to 16 sensors . We are open to any device that would be able to communicate with our python application.

We are looking for someone that can write the code for the micro processor unit and send information about the port telling us if it is occupied or not.

Please respond with pricing to do this and a recommended method.
