A variety of free resources are available online to help in learning Python coding. A (very) partial list includes:
Google's Python Class: Google, a notably dedicated user of Python, teaches an intensive 2-day class in Python, which it describes as being "for people with a little bit of programming experience who want to learn Python." The materials for this class, including recorded lectures, written materials and coding exercises, are available online.
Coursera's Python for Everybody Specialization: Consisting of a series of 4 online courses prepared by the University of Michigan, these courses may be taken at the student's convenience. Unless the student wishes to be granted a certificate at the conclusion of the courses, they may be taken for free.
