In Python, how do I split a string and keep the separators?

Background thread with QThread in PyQt
I have a program which interfaces with a radio I am using via a gui I wrote in PyQt. Obviously one of the main functions of the radio is to transmit data, but to do this continuously, I have to loop the writes, which causes the gui to hang. Since I have never dealt with threading, I tried to get rid of these hangs using QCoreApplication.processEvents(). The radio needs to sleep between transmissions, though, so the gui still hangs based on how long these sleeps last.

Installing python module within code
