The third part of the course is a good introduction to the capability of Python in writing search codes and in scraping the web and other applications. Assignments are more difficult to tackle than in the previous two courses probably because the materials needed to solve them were either not well explained or were explained in later lessons. For example, the instruction for a particular assignment gave a starting sample code that was claimed to be the closest to the code to do the assignment, a statement that turned out to be wrong. It was not close to it at all. This area should be looked into for future learners. The learners' minds should be prepared from the beginning that there might be a need to go outside the course materials to tackle some assignments.

Overall, again, the course is an excellent introduction to what Python can do in search programs using regular expressions and in scraping the web and other applications. To be very good at these topics, like any other courses, learners will need extensive practice on their own, as most of the assignments were completed through a hand-holding technique using the provided sample codes. 

Overall, I am happy with what I am learning in python programming, and perhaps, I would use this new knowledge to work as a web developer someday. Thank you, Dr Charles, University of Michigan, and Coursera. Keep up the good work of providing affordable and accessible education.
