I have a new udemy course available on PyQt5 programming. This is not a GIS course but PyQt5 programming is an essential skill for building QGIS plug-ins and very useful for other python based geospatial applications.
Use coupon code PYQTYT to get this course for $9.99 until Sept 1. More info at https://www.udemy.com/course/pyqt5-fr...
