Joshua Willman began using Python in 2015, when his first task was to build neural networks using machine learning libraries, including Keras and Tensorflow, for image classification. While creating large image data sets for his research, he needed to build a GUI that would simplify the workload and labeling process, which introduced him to PyQt. He currently works as a Python Developer and Instructor, designing courses to help others learn about coding in Python for game development, AI and machine learning, and programming using microcontollers. More recently, he set up the site Red Huli to explore his and others’ interests in using Python and programming for creative purposes.
