So far we've created a window and added a simple push button widget to it, but the button doesn't do anything. PyQt's signals and slots are thread safe, so you can use them to establish interthread communication as well as to share data between threads. You can connect signals emitted from a thread to slots within the thread or within a different thread. This means that you can execute code in a thread as a response to a signal emitted in the same.

Slots is the name Qt uses for the receivers of signals. In Python any function (or method) in your application can be used as a slot -- simply by connecting the signal to it. If the signal sends data, then the receiving function will receive that data too. PyQt supports many type of signals, not just clicks.
