Although ESRI offers fantastic training courses, sometimes I must supplement my professional development outside of work and fund training for myself. I found this course from Udemy on sale for $12.99, down from $200, https://www.udemy.com/share/100s6UB0MYcV9UQXo=/ ArcPy for Python Devlopers using ArcGIS Pro by Graeme Browning. So far this is a great course and for $13 bucks you cannot beat the price (well, maybe you could perhaps;)
